How to define piecewise functions - jc_63 - 12-29-2013 06:16 PM
Hello, i try to define a piecewise function in SYMB view like this :

In Plot view, i see F1(X) and F2(X) undefined :

How can i resolve this ? Thanks.

You could also use the old standby of (2*X)/(X<5) which works on any calculator if it has a piecewise operator or not.
