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 the Mathematica book: Section 1.4.5Section 3.3.7.
  • See also: TrigExpand, TrigFactor, TrigToExp, Simplify, FullSimplify.
