Note: These examples use the same x, y, and z Window variable values as a ZoomStd viewing cube. If you use ZoomStd, press Z to look down the z axis. Notes About Implicit Plots For an implicit plot: • The ncontour Window variable has no affect. Only the z=0 contour is drawn, regardless of the value of ncontour. The displayed plot shows where the implicit form intersects the xy plane. • You can use the cursor keys to animate the plot. • You cannot trace (...) the implicit plot itself. However, you can trace the unseen wire frame graph of the 3D equation. • It may take awhile to evaluate the equation initially. • Because of possible long evaluation times, you first may want to experiment with your 3D equation by using Style=WIRE FRAME. The evaluation time is much shorter. Then, after you're sure you have the correct Window variable values, set Style=IMPLICIT PLOT. 8Í Example: Implicit Plot of a More Complicated Equation You can use the IMPLICIT PLOT graph format style to plot and animate a complicated equation that cannot be graphed otherwise. Although it may take a long time to evaluate such a graph, the visual results can justify the time required. 3D Graphing 407
