# TrigFactor

TrigFactor[expr]

factors trigonometric functions in expr.

# Details • 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.
