I purchased my HP Prime today and I really enjoy. Your app for 3D Graphing is incredible.

I have a couple of questions though. Is there any way I can see the values on the box? For instance, if I graph an upper cone: f(x,y) = sqrt(x^2 + y^2), I see the wonderful drawing, but I do not see any values for where they intersect the box. Is there a way I can view this?

Additionally, do you know any Apps that would graph solutions for Differential Equations (similar to that on the TI-89)?

Thanks so much.

Would the trace feature do? Press the [.] key (or tap the screen and select trace mode). You can use the arrow keys to move the point to find the x,y,z values. Or is this not what you meant?
