Description

The development version of Mathematica contains extensive support for piecewise functions throughout the system. An arbitrary piecewise function (with a finite number of pieces) can be represented using the new piecewise construct. The function PiecewiseExpand allows users to transform an arbitrary composition of piecewise functions into a single piecewise function. These tools, as well as Mathematicaís condition solving capabilities, allow for efficient handling of piecewise functions in many contexts, including equation and inequality solving, optimization, computation of limits, derivatives, series, indefinite and definite integrals, solving of differential equations, and graphics.
