3D Graph Example
Example 1: To graph the hyperbolic paraboloid z = x 2
/2 – y 2
/8.
S ClassPad Operation
(1) In the 3D Graph application, make the 3D Graph Editor window active.
(2) Tap to display the View Window dialog box, and then configure the parameters
shown below.
xmin = –3 xmax = 3 xgrid = 25
ymin = –3 ymax = 3 ygrid = 25
angle Q = 45 angle F = 70
• Except for angle Q , all of the above settings are initial defaults.
• After everything is the way you want, tap [OK] to close the View Window dialog box.
(3) Tap line z 2 on the 3D Graph Editor window, and then input x 2 /2 – y 2 /8.
; 7:8:
(4) Press .
• This stores the expression you input and selects it, which is indicated by the button
changing to “ ”.
(5) Tap to graph the expression.

Drawing a 3D Graph
• Here, you can use the cursor key to rotate the graph on the display. On the 3D
Graph window, you can rotate the graph image by dragging with the stylus. For more
