Piecewise Function

Piecewise Function

 Top  Previous  Next

A piecewise function or expression can be created using the Piecewise symbol:

piecewise symb 

or the built-in function - piecewise({expression1, domain1},{expression2,domain2}...,{last expression, otherwise}).  The reserved word, "otherwise" is an option available for the last condition.

Here we show how to enter the sequence of values, followed by conditions:

  • Create a function draw_function_button .
  • Double click the equation to edit.

  • From the edit box click the Piecewise icon in the Symbols toolbox. Four small gray boxes will appear, including the one containing the original equation.

  • Fill in your piecewise parameters - equations in the left column and their domain in the right column.  To expand the function, click the Piecewise icon again  for an additional row.

Here's the finished piecewise function:
