Chebyshev's method is a recursive algorithm for computing the th multiple angle formula for the cosine function. If we define:
then the algorithm is given as:
where:
a) Using trigonometric identities (or otherwise), derive the recursive algorithm.
b) Find a closed polynomial form for .
c) Compute
d) Compute
