Solution 16189: Creating a 3D Graph of a Surface On a TI-89 Family, TI-92 Family, or Voyage™ 200 Graphing Calculator.
How do I create a 3D graph of a surface on a TI-89 family, TI-92 family, or Voyage 200 graphing calculator?
Please see the below example for graphing a surface in 3D on a TI-89 family, TI-92 family, or Voyage 200 graphing calculator:
Example: Graph z=y^2-x^2
1) Press [MODE] in 'Graph' select 5:3D then press [ENTER] [ENTER] to change the mode to 3D.
2) Press [♦][Y=].
3) Input the equation [y][^][-][x][^] in z1.
4) Press [♦][GRAPH].
The graph can be viewed at different angles by pressing the arrow keys.
Additional information on 3D graphing can be found in the TI-89 family, TI-92 family and Voyage 200 guidebooks.
