TRIGSIMP _ _ _ _ _ _ _ _ _ _ _ _ package
Author: Wolfram Koepf
TRIGSIMP is a useful tool for all kinds of trigonometric and hyperbolic simplification and factorization. There are three procedures included in TRIGSIMP: trigsimp, trigfactorize and triggcd. The first is for finding simplifications of trigonometric or hyperbolic expressions with many options, the second for factorizing them and the third for finding the greatest common divisor of two trigonometric or hyperbolic polynomials.
