I have a class where you enter control points for a catmull-rom spline, and then it returns a list of points running along the spline.
What points would I need to enter to create a circle?

i have this huge function and i am wondering how to make it recursive. i have the base case which should never come true, so it should always go to else and keep calling itself with the variable t increases. any help would be great
thanks

I'm trying to calculate the sunset / rise times using python based on the link provided below.
My results done through excel and python do not match the real values. Any ideas on what I could be doing wrong?

Hi Guys,
I'm constructing a geolocation based application and I'm trying to figure out a way to make my application realise when a user is facing the direction of the given location (a particular long / lat co-ord). I've got the math figured, I just have the triangle to construct.
//UPDATE
So…

so I'm trying to make a program that will output the sum, average, and smallest and largest values. I have everything basically figured out except the smallest and largest values are outputting 2147483647 and -2147483647, which I believe are the absolute smallest and largest values that Java will…

I've heard many times that all programming is really a subset of math. Some suggest that OO, at its roots, is mathematically based. I don't get the connection. Aside from some obvious examples:
using induction to prove a recursive algorithm
formal correctness proofs
functional languages
lambda calculus
asymptotic…

I have a path that is defined by a concatenation of Catmull-Rom splines. I use the static method Vector2.CatmullRom in XNA that allows for interpolation between points with a value going from 0 to 1.
Not every spline in this path has the same length. This causes speed differences if I let the weight…

I would like to fit my data using spline(y~x) but all of the examples that I can find use a spline with smoothing, e.g. lm(y~ns(x), df=_).
I want to use spline() specifically because I am using this to do the analysis represented by the plot that I am making.
Is there a simple way to use spline()…

I have a bunch of coordinates which are the control points of a clamped uniform cubic B-spline on the 2D plane. I would like to draw this curve using Cairo calls (in Python, using Cairo's Python bindings), but as far as I know, Cairo supports Bézier curves only. I also know that the segments of a…
