•Press „ô, simultaneously if in RPN mode, to access to the PLOT SETUP window.

•Change TYPE to Fast3D. ( @CHOOS!, find Fast3D, @@OK@@).

•Press ˜and type ‘X^2+Y^2’ @@@OK@@@.

•Make sure that ‘X’ is selected as the Indep: and ‘Y’ as the Depnd: variables.

•Press L@@@OK@@@ to return to normal calculator display.

•Press „ò, simultaneously if in RPN mode, to access the PLOT WINDOW screen.

•Keep the default plot window ranges to read:

X-Left:-1	X-Right:1
Y-Near:-1	Y-Far: 1
Z-Low: -1	Z-High:	1
Step Indep: 10	Depnd:	8

Note: The Step Indep: and Depnd: values represent the number of gridlines to be used in the plot. The larger these number, the slower it is to produce the graph, although, the times utilized for graphic generation are relatively fast. For the time being we’ll keep the default values of 10 and 8 for the Step data.

•Press @ERASE @DRAW to draw the three-dimensional surface. The result is a wireframe picture of the surface with the reference coordinate system shown at the lower left corner of the screen. By using the arrow keys (š™—˜) you can change the orientation of the surface. The orientation of the reference coordinate system will change accordingly. Try changing the surface orientation on your own. The following figures show a couple of views of the graph:
