An idea for a sine and cosine algorithm occured to me the other day, so I tried it out by hand, then tested it in python, and it works!
I believe it falls into the category of CORDIC algorithms, iterative algorithms that exponentially approach the correct answer. This means it has an additional parameter that controls how many times to iterate, and therefore, how accurate the answer must be.

Scene explains how it works, and has a function for the 0°-90° range ready to go.

This is cool! Would it be possible to make a scene detailing a square root algorithm? Bonus points if it works for all radicals and not just square roots. :lol: :lol: :lol:

When I run the simulation, the entire thing flies apart and falls down into the infinite depths of Algodoo never-land. What went wrong? :s

Oh right, it's not exactly a scene to /run/, the real asset is the algorithm, and the understanding on how it works.

Implementing Taylor Series for sine and cosine in C also accomplishes the same result, but I like the thought behind, and the brevity of, your algorithm.
