  • Using Taylor Polynomials Programmatically in Maple

    - by kzh
    I am trying to use a Taylor polynomial programmatically in Maple, but the following does not seem to work... T[6]:=taylor(sin(x),x=Pi/4,6);convert(T[6], polynom, x); f:=proc(x) convert(T[6], polynom, x); end proc; f(1); All of the following also do not work: f:=convert(T[6], polynom); f:=convert(T[6], polynom, x); f:=x->convert(T[6], polynom); f:=x->convert(T[6], polynom, x);. Is there a way of doing this without copying and pasting the output of convert into the definition of f?

  • Using Taylor Series to Avoid Loss of Precision

    - by Zachary
    I'm trying to use Taylor series to develop a numerically sound algorithm for solving a function. I've been at it for quite a while, but haven't had any luck yet. I'm not sure what I'm doing wrong. The function is f(x)=1 + x - sin(x)/ln(1+x) x~0 Also: why does loss of precision even occur in this function? when x is close to zero, sin(x)/ln(1+x) isn't even close to being the same number as x. I don't see where significance is even being lost. In order to solve this, I believe that I will need to use the Taylor expansions for sin(x) and ln(1+x), which are x - x^3/3! + x^5/5! - x^7/7! + ... and x - x^2/2 + x^3/3 - x^4/4 + ... respectfully. I have attempted to use like denominators to combine the x and sin(x)/ln(1+x) components, and even to combine all three, but nothing seems to work out correctly in the end. Any help is appreciated.

  • Need help programming with Mclauren series and Taylor series!

    - by user352258
    Ok so here's what i have so far: #include <stdio.h> #include <math.h> //#define PI 3.14159 int factorial(int n){ if(n <= 1) return(1); else return(n * factorial(n-1)); } void McLaurin(float pi){ int factorial(int); float x = 42*pi/180; int i, val=0, sign; for(i=1, sign=-1; i<11; i+=2){ sign *= -1; // alternate sign of cos(0) which is 1 val += (sign*(pow(x, i)) / factorial(i)); } printf("\nMcLaurin of 42 = %d\n", val); } void Taylor(float pi){ int factorial(int); float x; int i; float val=0.00, sign; float a = pi/3; printf("Enter x in degrees:\n"); scanf("%f", &x); x=x*pi/180.0; printf("%f",x); for(i=0, sign=-1.0; i<2; i++){ if(i%2==1) sign *= -1.0; // alternate sign of cos(0) which is 1 printf("%f",sign); if(i%2==1) val += (sign*sin(a)*(pow(x-a, i)) / factorial(i)); else val += (sign*cos(a)*(pow(x-a, i)) / factorial(i)); printf("%d",factorial(i)); } printf("\nTaylor of sin(%g degrees) = %d\n", (x*180.0)/pi, val); } main(){ float pi=3.14159; void McLaurin(float); void Taylor(float); McLaurin(pi); Taylor(pi); } and here's the output: McLaurin of 42 = 0 Enter x in degrees: 42 0.733038-1.00000011.0000001 Taylor of sin(42 degrees) = -1073741824 I suspect the reason for these outrageous numbers goes with the fact that I mixed up my floats and ints? But i just cant figure it out...!! Maybe its a math thing, but its never been a strength of mine let alone program with calculus. Also the Mclaurin fails, how does it equal zero? WTF! Please help correct my noobish code. I am still a beginner...

  • Function approximation with Maclaurin series

    - by marines
    I need to approx (1-x)^0.25 with given accuracy (0.0001 e.g.). I'm using expansion found on Wikipedia for (1+x)^0.25. I need to stop approximating when current expression is less than the accuracy. long double s(long double x, long double d) { long double w = 1; long double n = 1; // nth expression in series long double tmp = 1; // sum while last expression is greater than accuracy while (fabsl(tmp) >= d) { tmp *= (1.25 / n - 1) * (-x); // the next expression w += tmp; // is added to approximation n++; } return w; } Don't mind long double n. :P This works well when I'm not checking value of current expression but when I'm computing 1000 or more expressions. Domain of the function is <-1;1 and s() calculates approximation well for x in <-1;~0.6. The bigger the argument is the bigger is the error of calculation. From 0.6 it exceeds the accuracy. I'm not sure if the problem is clear enough because I don't know English math language well. The thing is what's the matter with while condition and why the function s() doesn't approximate correctly.

  • DOM: element created with cloneNode(true) missing element when added to DOM

    - by user149327
    I'm creating a tree control and I'm attempting to use a parent element as a template for its children. To this end I'm using the element.cloneNode(true) method to deep clone the parent element. However when I insert the cloned element into the DOM it is missing certain inner elements despite having an outerHTML value identical to its parent. Surprisingly I observe the same behavior is in IE, Firefox, and Chrome leading me to believe that it is by design. This is the HTML for the node I'm attempting to clone. <SPAN class=node><A class=nodeLink href="/SparklerRestService2.aspx?q={0}" name=http://dbpedia.org/data/Taylor_Swift.rdf> <IMG class=nodeIcon alt="Taylor Swift" src="images/node.png"><SPAN class=nodeText>Taylor Swift</SPAN></A><SPAN class=nodeDescription>Taylor Swift is a swell gall who is realy great.</SPAN></SPAN> Once I've cloned the node using cloneNode(true) I examine the outerHTML property and find that it is indeed identical to the original. <SPAN class=node><A class=nodeLink href="/SparklerRestService2.aspx?q={0}" name=http://dbpedia.org/data/Taylor_Swift.rdf><IMG class=nodeIcon alt="Taylor Swift" src="images/node.png"><SPAN class=nodeText>Taylor Swift</SPAN></A><SPAN class=nodeDescription>Taylor Swift is a swell gall who is realy great.</SPAN></SPAN> However when I insert it into the DOM and inspect the result using FireBug I find that the element has been transformed: <span class="node" style="top: 0px; left: 0px;"<a class=nodeLink href="/SparklerRestService2.aspx?q={0}" name=http://dbpedia.org/data/Taylor_Swift.rdf>Taylor Swift</a><span class="nodeDescription">It's great</span></span> Notice that the grandchildren of the node (the image tag and the span tag surrounding "Taylor Swift") are missing, although strangely the great grandchild "Taylor Swift" text node has made it into the tree. Can anyone shed some light on this behavior? Why would nodes disappear after insertion into the DOM, and why am I seeing the same result in all three major browser engines?

  • First Look - Oracle Data Mining

    - by kimberly.billings
    In his blog, JT on EDM, James Taylor shares his analysis of Oracle Data Mining, including its new GUI and Exadata integration. While Oracle Data Mining has been available for a while, it is now easier to access and try via the Amazon Cloud. Using the Oracle 11gR2 Data Mining Amazon Machine Image (AMI), you can launch an Oracle Data Mining-enabled instance directly through Amazon Web Services (AWS) and connect to it using the Oracle Data Miner graphical user interface. The new Oracle Data Mining GUI, which will be available to beta customers soon, provides more graphics, the ability to define, save and share analytical "work flows" to solve business problems, and provides more automation and simplicity. Taylor comments that, "the UI looks to have a nice look and feel including graphical model development flows, easy access to the data, nice little micro graphs when browsing data records and more." On using Oracle Data Mining with Exadata, Taylor writes, "Oracle says that the use of the ODM routines in the Exadata kernel is faster than running a native ODM model in the database by a factor of 2 and that this increases as more joins are used. This could mean that ODM outperforms even third party in-database analytics." Taylor concludes his blog with a positive overall review, stating that "ODM is a nice product for Oracle database customers and well worth looking into. The new UI will only make it more so." Read the blog. var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); try { var pageTracker = _gat._getTracker("UA-13185312-1"); pageTracker._trackPageview(); } catch(err) {}

  • How to get only one row for each distinct value in the column ?

    - by Chavdar
    Hi Everybody, I have a question about Access.If for example I have a table with the following data : NAME | ADDRESS John Taylor | 33 Dundas Ave. John Taylor | 55 Shane Ave. John Taylor | 786 Edward St. Ted Charles | 785 Bloor St. Ted Charles | 90 New York Ave. I want to get one record for each person no matter of the address.For example : NAME | ADDRESS John Taylor | 33 Dundas Ave. Ted Charles | 90 New York Ave. Can this be done with queries only ? I tried using DISTINCT, but when I am selecting both columns, the combination is allways unique so I get all the rows. Thank you !

  • How do I stop XNA/Visual Studio from rebuilding my content project every time I build?

    - by Phil Quinn
    My group and I are working on a game in XNA 4.0 with Visual Studio 2010/2012. The main solution has 6 projects: 2 XNA game projects (1 executable/ 1 class library), 1 WPF executable for the level editor, 2 standard class libraries, and a content project. Originally, the editor and engine XNA game projects had a content reference to separate content projects. Recently, I consolidated the content projects into one to simplify asset additions. Since pushing these changes to our git repo, certain members of my group have been experiencing weird build issues. Every time they run the project, they have to re-build all of the assets. This happens regardless of whether any changes were made, even if they just run the project directly after building. I've taken a few steps to figure out why this is happening. Below is the MSBuild output set on Normal verbosity. The seemingly important part is at 4, with the line 4> Rebuilding all content because build settings have changed 1>------ Build started: Project: Engine.Core, Configuration: Debug x86 ------ 1>Build

Also, I can post more details upon request if this isn't thorough enough.

  • Fork dead SVN based project on GitHub

    - by Quinn Bailey
    I previously asked this at stack overflow but it was closed, I believe because 'programmers' is a more appropriate venue for this question. I have done some work on the SVN Importer project (Apache license), which appears to be effectively dead (no published changes in 5 years). I have a login to their svn server but do not have commit rights. At any rate, I'd like to convert this project to Git and push my own changes to GitHub. The GitHub site suggests the svn2git tool for converting svn projects to Git, so I was planning to convert the SVN repository to Git, add my changes, and then push this Git repository to GitHub. I'm wondering, what are the legal requirements and common conventions of this process? Is it acceptable to clone the entire history of the project and move it to GitHub? Also, even though this is essentially a dead project, once I've translated the repository to Git should I put all of my commits onto a non master branch or is it acceptable to use master in this case?

  • how to find available wireless networks

    - by Quinn
    I'm using an HP Pavilion dv6000 I've looked at other answers similar to this question how ever when I look at my network symbol it doesn't say anything that the answer below says "Make sure that your wifi hardware switch is on or not. It is either F2 or F12 or near to it. Once the switch is enabled, there is a small fan-like applet on the top panel (Gnome Network Manager), fourth from the right. Click on it and if there is no tick mark on the option 'Enable Wireless', enable it. Wait till your wifi connection name appears." it how says 'Enable Networking' my wi-fi switch is on and I've tried using terminal to kill the applet as another answer suggests trying. Does anyone have any other ideas that might help? Just in case anybodies curious as to how I'm posting this I'm on my other ubuntu laptop that's running an older version.

  • Jquery Flexslider - can't see navigational images (manualControl)

  • How to Get All the Windows 8 Editions on One Install Disk

    - by Taylor Gibb
    There are a lot of different versions of Windows, but you probably didn’t know that short of the Enterprise edition, the disc or image that you own contains all versions for that architecture. Read on to see how we can use them to make a universal Windows 8 install disc. Things You Will Need A x86 Version of Windows 8 A x64 Version of Windows 8 A x86 Version of Windows 8 Enterprise A x64 Version of Windows 8 Enterprise A Windows 8 PC Note: While we will use all the images above you don’t really need the Enterprise Edition. You could always leave out parts of the tutorial if you know what you are doing, if you are not comfortable with that and still want to follow through you could always grab the Enterprise evaluation images that are available for free to the public, on MSDN. Getting Started To get started you will need to Download the Windows 8 ADK from Microsoft. Once downloaded go ahead and install it, you will only need the Deployment tools so be sure to uncheck the rest of the options. Lastly you will also need to create the following folder structure on the root of your C:\ drive to make things a bit easier. C:\Windows8Root C:\Windows8Root\x86 C:\Windows8Root\x64 C:\Windows8Root\Enterprisex86 C:\Windows8Root\Enterprisex64 C:\Windows8Root\Temp C:\Windows8Root\Final OK lets get started. Making The Image The first thing we need to do is create a base image, so mount the x86 version of Windows 8 and copy its files to: C:\Windows8Root\Final Now move the install.wim file from: C:\Windows8Root\Final\sources To: C:\Windows8Root\x86 Next go ahead and copy the install.wim file from the other 3 images, Windows 8 x64, Windows 8 Enterprise x86 and Windows 8 Enterprise x64 to the respective folders in Windows8Root, the install.wim file can be located at: D:\sources\install.wim Note: The above assumes that the images are always mounted at drive D. Remember that each install.wim is different so don’t copy them to the wrong directories or the rest of the tutorial wont work. Next switch to the Metro Start Screen and open the Deployment and Imaging Tools Environment. Note: If you are not a local administrator on your PC, you will need to right-click on it and choose to run it as an administrator. Now run the following commands: Dism /Export-Image /SourceImageFile:c:\Windows8Root\x86\install.wim /SourceIndex:2 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8″ /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\x86\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Pro” /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\x86\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Pro with Media Center” /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\Enterprisex86\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Enterprise” /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\x64\install.wim /SourceIndex:2 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8″ /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\x64\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Pro” /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\x64\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Pro with Media Center” /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\Enterprisex64\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Enterprise” /compress:maximum Next navigate to: C:\Windows8Root\sources\ And create a new text file. You will need to call it: EI.cfg Then edit it to look like the following: The last thing we need to do is work some magic to get Windows Media Center added to the WMC editions of Windows 8. For that I have written a little script to make it easier for everybody, you can grab it here. Once you have downloaded it extract it. In order to use it right-click in the bottom left hand corner of the screen, and open an elevated command prompt. Then go ahead and paste the following into the command prompt window. powershell.exe -ExecutionPolicy Unrestricted -File C:\Users\Taylor\Documents\HTGWindows8Converter.ps1 Note: You will need to replace the path to the script, another thing to note is that if the path you replace it with has spaces you will need to enclose the path in quotes. The script should kick off straight away and has some progress bars you can watch while it does its thing. Half way through another Window will pop open, which will start creating your final ISO image. When its complete, close the command prompt and you should have an ISO image on the root of your C drive called: HTGWindows8.iso That’s all there is to it. 7 Ways To Free Up Hard Disk Space On Windows HTG Explains: How System Restore Works in Windows HTG Explains: How Antivirus Software Works

  • Cut Caseload Costs, Speed Service Delivery For Social Services

    - by michael.seback
    Lower Caseload Costs, Speedier Service Delivery with New Oracle Social Services Solution Oracle has just introduced a new solution for social services agencies that's designed to help case workers address the challenges of rising workloads and growing demands by citizens for additional services. In the past, IT departments developed custom software in an effort to meet program outcomes. "Because this capability is out of the box with the Oracle solution, there's less complexity for organizations and an overall lower total cost of ownership," says Kimberly Ellison-Taylor, Oracle's executive director of health and human services. "Self service brings costs down to just pennies per interaction and makes it possible for clients to receive government services more quickly," Ellison-Taylor says. read more

  • Thank You For Visiting Us At Oracle OpenWorld And JavaOne

    - by Brandye Barrington
    Thanks to everyone who visited us at the Oracle OpenWorld and JavaOne conferences last week. We always enjoy putting faces with names and meeting those of you who are certified or are interested in Certification. Personally, I spent my week on sunny Taylor street at the Java Certification Zone in Taylor Street Cafe.  I talked to over 100 people last week about certification and handed out over 65 ribbons. The Oracle Certification Lounge at OpenWorld, at Moscone South enjoyed more than 200 visitors over the week. Both locations offered scheduled speakers and available experts, in addition to answers to all of your certification questions and account help when needed. We look forward to this opportunity every year to connect with you face to face. If you didn't make it out this year, we hope to see you next year - perhaps we will be so lucky as to enjoy another unseasonably warm week in San Francisco! Stay tuned to our blog for some customer success stories that we were able to record last week.

  • How to get the Blur event to fire for the document on the iPhone?

    - by Ian Storm Taylor
    Does anyone know how to get the blur event to fire on the document for the iPhone? I'm trying to get it to fire either when a user changes windows in Safari, or when they open their bookmarks or when they decide to add the page to their homescreen. But none of these are firing it. Here's my code: $(document).blur( function () { document.title = "Ian Taylor"; }); I've tried "document", "window", "'body'". Nothing seems to work.

  • Runge-Kutta (RK4) integration for game physics

    - by Kai
    Gaffer on Games has a great article about using RK4 integration for better game physics. The implementation is straightforward but the math behind it confuses me. I understand derivatives and integrals on a conceptual level but I haven't manipulated equations in a long time. Here's the brunt of Gaffer's implementation: void integrate(State &state, float t, float dt) { Derivative a = evaluate(state, t, 0.0f, Derivative()); Derivative b = evaluate(state, t+dt*0.5f, dt*0.5f, a); Derivative c = evaluate(state, t+dt*0.5f, dt*0.5f, b); Derivative d = evaluate(state, t+dt, dt, c); const float dxdt = 1.0f/6.0f * (a.dx + 2.0f*(b.dx + c.dx) + d.dx); const float dvdt = 1.0f/6.0f * (a.dv + 2.0f*(b.dv + c.dv) + d.dv) state.x = state.x + dxdt * dt; state.v = state.v + dvdt * dt; } Can anybody explain in simple terms how RK4 works? Specifically, why are we averaging the derivatives at 0.0f, 0.5f, 0.5f, and 1.0f? How is averaging derivatives up to the 4th order different from doing a simple euler integration with a smaller timestep? After reading the accepted answer below, and several other articles, I have a grasp on how RK4 works. To answer my own questions: Can anybody explain in simple terms how RK4 works? RK4 takes advantage of the fact that we can get a much better approximation of a function if we use its higher-order derivatives rather than just the first or second derivative. That's why the Taylor series converges much faster than Euler approximations. (take a look at the animation on the right side of that page) Specifically, why are we averaging the derivatives at 0.0f, 0.5f, 0.5f, and 1.0f? The Runge-Kutta method is an approximation of a function that samples derivatives of several points within a timestep, unlike the Taylor series which only samples derivatives of a single point. After sampling these derivatives we need to know how to weigh each sample to get the closest approximation possible. An easy way to do this is to pick constants that coincide with the Taylor series, which is how the constants of a Runge-Kutta equation are determined. This article made it clearer for me: http://web.mit.edu/10.001/Web/Course%5FNotes/Differential%5FEquations%5FNotes/node5.html. Notice how (15) is the Taylor series expansion while (17) is the Runge-Kutta derivation. How is averaging derivatives up to the 4th order different from doing a simple euler integration with a smaller timestep? Mathematically it converges much faster than doing many Euler approximations. Of course, with enough Euler approximations we can gain equal accuracy to RK4, but the computational power needed doesn't justify using Euler.

  • Can I disallow printing with parent controls on Snow Leopard?

    - by Quinn Taylor
    I have two children under 4 who are quite computer-savvy, and have their own account managed by parental controls to restrict what they can do an see. However, I haven't found a way to disallow them from printing, and I'm looking for a way do so. Their pictures of Sesame Street and Word World are cute and all, but I'd like to be in control of what (or even if) they print. (Our printer is connected wirelessly, not directly to the Mac.) I know I can add more time or authorize use of a given application by providing my password — can I do something similar for printing, such as approving or denying particular print jobs?

  • Have an unprivileged non-account user ssh into another box?

    - by Daniel Quinn
    I know how to get a user to ssh into another box with a key: ssh -l targetuser -i path/to/key targethost But what about non-account users like apache? As this user doesn't have a home directory to which it can write a .ssh directory, the whole thing keeps failing with: $ sudo -u apache ssh -o StrictHostKeyChecking=no -l targetuser -i path/to/key targethost Could not create directory '/var/www/.ssh'. Warning: Permanently added '<hostname>' (RSA) to the list of known hosts. Permission denied (publickey). I've tried variations using -o UserKnownHostsFile=/dev/null and setting $HOME to /dev/null and none of these have done the trick. I understand that sudo could probably fix this for me, but I'm trying to avoid having to require a manual server config since this code will be deployed on a number of different environments. Any ideas? Here's a few examples of what I've tried that don't work: $ sudo -u apache export HOME=path/to/apache/writable/dir/ ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=path/to/apache/writable/dir/.ssh/known_hosts -l deploy -i path/to/key targethost $ sudo -u apache ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=path/to/apache/writable/dir/.ssh/known_hosts -l deploy -i path/to/key targethost $ sudo -u apache ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -l deploy -i path/to/key targethost Eventually, I'll be using this solution to run rsync as the apache user.

  • How to configure Dovecot to not serve large emails to high-latency clients?

    - by Daniel Quinn
    I have a Dovecot mailserver running at home on a flaky cable connection. For the most part, the IMAP functionality works beautifully, but I'd like to add one feature if I can: I want Dovecot not to serve large messages to high-latency clients. That is to say, if someone decides that it's a good idea to send me a 9.3mb email to me, I don't want to get it unless I'm on my LAN at home. This can't be an uncommon request, but I'm having trouble finding the configuration option in their documentation. Any ideas and/or good keywords to use in Googling would be awesome.

  • Weird console problem in linux, usually right before OOM

    - by Kevin Quinn
    So I've noticed this happen more than once. If I remember correctly, this usually happens right before OOM, and/or kernel panic that if you type into a tty and then try to backspace it, the same characters are printed back in reverse. This has been merely an interesting oddity to me in the past, but it happened again recently, and I've gotten more curious about what's actually causing that. (Is it sending the characters back to STD_OUT or something?) Does anyone have any idea? I have a feeling the answer will be interesting. Just so I'm clear, if you typed hello world, then tried to backspace it: hello world..dlrow olleh
