FilledSmallSquareFunctionExpand[expr] tries to expand out special and certain other functions in expr, when possible reducing compound arguments to simpler ones.

FilledSmallSquareFunctionExpand[expr, assum] expands using assumptions.

FilledSmallSquareFunctionExpand uses a large collection of rules.

FilledSmallSquareFunctionExpand applies to certain trigonometric functions as well as special functions.

FilledSmallSquareFunctionExpand is automatically called by FullSimplify.

FilledSmallSquare Assumptions in FunctionExpand can be specified as in Simplify.

FilledSmallSquare Example: FunctionExpand[expr, x Reals] performs expansion assuming that x is real.

FilledSmallSquare See The Mathematica Book: Section 3.2.13.

FilledSmallSquare Implementation Notes: see section A.9.5.

FilledSmallSquare See also: TrigExpand, TrigToExp, ComplexExpand, FullSimplify.
