Vector Equation of Plane
1. On the top right, click on the "rotate" icon between the magnet and the cube to rotate the diagram (you can also change the speed of rotation).
2. You can slide to change the values of λ and μ on the left to show how the point with position vector r = a + λb + μc traces out a plane
3. Click on the successive checkboxes to show the plane, the normal n, and to hide the position and direction vectors a, b and c.
4. You can slide to change the values of λ and μ on the left to show that the projection of r onto the normal is a constant.
