Taylor polynomials are terrific local approximations but poor global approximations. Taylor polynomials are optimal in some sense near their center, but are seldom the best choice over a large interval. This post will look at approximating sin(πx) over [-1, 1] with fifth degree polynomials. First, this plot compares the approximation error for a fifth order […]The post Polynomial approximations to sine first appeared on John D. Cook.
