An Elementary Algorithm to Evaluate Trigonometric Functions to High Precision
Johansson, B. Tomas
International Journal of Mathematical Education in Science and Technology, v49 n1 p131-137 2018
Evaluation of the cosine function is done via a simple Cordic-like algorithm, together with a package for handling arbitrary-precision arithmetic in the computer program Matlab. Approximations to the cosine function having hundreds of correct decimals are presented with a discussion around errors and implementation.
