GRAPH 3D v2.425 (20-FEB-2017)

[LCieParagon]

Hello. I'm a Calculus III / Differential Equations teacher.

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.
