TrigReduce

Updated In 6 Graphic
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.
  • TrigReduce automatically threads over lists, as well as equations, inequalities and logic functions.
