TrigExpand

FilledSmallSquare TrigExpand[expr] expands out trigonometric functions in expr.

FilledSmallSquare TrigExpand operates on both circular and hyperbolic functions.

FilledSmallSquare TrigExpand splits up sums and integer multiples that appear in arguments of trigonometric functions, and then expands out products of trigonometric functions into sums of powers, using trigonometric identities when possible.

FilledSmallSquare See Section 1.4.5 and Section 3.3.7.

FilledSmallSquare See also: TrigFactor, TrigReduce, TrigToExp, Expand, FunctionExpand, Simplify, FullSimplify.

FilledSmallSquare New in Version 3.
