# Representation Formulas

Oftentimes, mathematical expressions are not in the desired form for the purpose of their application. Representations are alternate forms of functions or expressions that make them easier to understand or use. Common representations are those that involve integrals, limits, infinite products or sums, power series, or representations through special functions. Wolfram|Alpha can find alternate representations of a specified form for a given mathematical function.
