I have the following piece of pseudo-C/Java/C# code:
int a[]= { 30, 20 };
int b[] = { 40, 50 };
int c[] = {12, 12};
How do I compute the cross-product ABxAC?

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 figured this answer had been asked before, so I searched, but I couldn't find anything. Granted, there are a ton of Ruby Array questions, so it might be there, just buried.
In any case, I'm trying to reduce a cross-product of ranges, returning a sum of all elements of the cross-product that meet…

I read this post explaining a method to understand if the angle between 2 given vectors and the normal to the plane described by them, is clockwise or anticlockwise:
public static AngleDir GetAngleDirection(Vector3 beginDir, Vector3 endDir, Vector3 upDir)
{
Vector3 cross = Vector3.Cross(beginDir…

how can I get the list of cross product pairs from a list of arbitrarily long lists in python? e.g.
a = [1,2,3]
b = [4,5,6]
crossproduct(a,b) should yield [[1,4], [1, 5], [1,6], ...]
thanks.
