TrigReduce

TrigReduce[expr] rewrites products and powers of trigonometric functions in expr in terms of trigonometric functions with combined arguments.

TrigReduce operates on both circular and hyperbolic functions.

Given a trigonometric polynomial, TrigReduce typically yields a linear expression involving trigonometric functions with more complicated arguments.

See Section 1.4.5 and Section 3.3.7.
