Creating a piece wise function

A piece wise function is a function whose definition is given differently on disjoint subsets of its domain. In Casyopée, it is done by using two or more already defined functions, using the menu Create function PieceWise. A form opens with checkboxes for selecting functions.

Select the functions f, g and h and press OK.
 

A new function is created; checking at the bottom of the graphic tab one can see its curve.
