FilledSmallSquareTrigExpand[expr] expands out trigonometric functions in expr.

FilledSmallSquareTrigExpand operates on both circular and hyperbolic functions.

FilledSmallSquareTrigExpand 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 The Mathematica Book: Section 1.4.5 and Section 3.3.7.

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