However, that is not the case still waiting for further information. I believe it could until the last update. It may go back a few years let see. Do you have problems entering the Equation in the HP Prime? There should be no need for work around it in TextBook Style RE: HP Prime whats in the printing can be done. - Didier Lachieze - 01-11-2022 04:48 PM I don't have problems entering the equations in the Prime but the values of F1(X) and F2(X) in the Plot view are NaN. Here is how I would do it without the 'where' operator: [attachment=10267] [attachment=10268] You can also use the function PIECEWISE (see the on-calc help for more details): [attachment=10269] Note: in Textbook mode you can avoid specifying the second condition.

Thank you, I was trying the Piecewise now I see how that works.

It's not elegant, but it should work. The other way to do it if you wanted a strict bound is to do (2*X)/(X<1).
