Hello everyone:
This is ridiculous, but more ridiculus is the User's Manual. How can I enter an equation on the PLOT SETUP menu? (Left + 2D/3D buttons). I am trying to type "X^2 + Y^2", just like it says in the user's manual. When I hit enter, "too few arguments". The user manual also says "change Type to Fast 3D". I just never found those options.
I am getting irritated with a calculator said to be good. I switched from Texas to HP and now I get this. Can anyone help me with these questions?
thanks
