I just got an HP Prime and I don't know how to calculate functions with more than 1 variable.
For instance, if I have f(x,y) = 1/(xˆ2+yˆ2) and I want the values of (3,4) and also the graphic of this function, what should I do?
Thanks for the help,

It looks like you are looking for a 3D graphic.
Press the Apps key and select the Graph3D app there.
In the function seleciton screen, enter 1/(x²+y²), validate and press on PLOT you should see your graph. Use the touch screen to rotate it...
Press on Home key and type FZ1(1,2) ENTER to get the result of 0.2

Hi!, @LucasCordeiro :
You needed actualize the Firmware, Connectivity Kit and Emulator, from ... ftp://ftp.hp.com/pub/calculators/Prime
The ultimate version of Software 2.1.14181 (2018 10 16).
1) First delete the Connectivity Kit, Firmware and Virtual Emulator (if any), of your computer.
2) Install the three files and if have physics calculator, you can download the ultimate, from Connectivity Kit active.
You're Welcome !.
Best wishes and regards.

You can also use the Shift Define screen to create a 2 input function do perform your calculations... You will just not be able to graph it, or only graph it with regard to 1 variable.
