SOURCE: hi, I wonder how to
First you must configure your calculator to perform 3D graphics
1.The first line shown is Graph. Unfold the hidden menu list with the right arrow and choose Graph 5:3D
2. Press ENTER to validate.
Now you must define the surface you want to draw
1. Press the [diamond] key then [Y=] to get a list of function names, the first of which is z1
2. Enter the following function (or your own) z1=(x^3*y-y^3*x)/390
( x cubed times y -y cubed times x) divided by 390.
3 Press ENTER.
Graph the function
Press the [diamond] key then [GRAPH]
The graphing screen displays progress in %. When it is finished you will see a weird sombrero.
Hope it helps
