Differences in 3D and Function Graphing
This module assumes that you already know how to graph y(x) functions as described in
Basic Function Graphing. This section describes the differences that apply to 3D
equations.

Setting the Graph Mode
Use 3 to set
Graph = 3D before you define equations or set Window variables. The
Y= Editor and the Window Editor let you enter information for the current Graph mode
setting only.

Defining 3D Equations on the Y= Editor
The Y= Editor maintains an independent function list for each Graph mode setting. For
example, suppose:
• In FUNCTION graphing mode, you define a set of
y(x) functions. You change to 3D
graphing mode and define a set of
z(x,y) equations.
You can define 3D equations
for z1(x,y) through z99(x,y).
