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.
