# TrigFactor

 TrigFactor[expr]factors trigonometric functions in expr.
• TrigFactor operates on both circular and hyperbolic functions.
• TrigFactor splits up sums and integer multiples that appear in arguments of trigonometric functions, and then factors resulting polynomials in trigonometric functions, using trigonometric identities when possible.
• TrigFactor automatically threads over lists, as well as equations, inequalities, and logic functions.
