3D grapher
Instructions for use
This applet is meant to help you graph points and planes in 3D. By default, point P is (1,–2,3) and the plane visible is the standard x-y plane (given by z=0).
You may show or hide these by checking the corresponding checkbox below the graph.
To change the point, P, type in the x, y, and z coordinates as ordered triples. For example, (0,0,0) moves P to the origin.
To change the plane, type in an entire equation. For example, the y-z plane is given by x=0
