Plotting 3D is same as plotting 2D except your functions can use variable "y" in 3D mode. Continuing the example of the previous section, follow this step:

• Click on "3D" in Draw Attributes.

The 3D graph will be automatically plotted. If it didn't, then click on "Redraw All" button.

For better visualization you can rotate or zoom in the graph as explained in next section.
