Prof. James O’Brien EXTRA CREDIT page 15 of 16 5 points Given a plane and a sphere:
Plane:
Sphere: ˆ
n·x+f =0 c − x − r = 0 Write out an equation that will, for the case where the plane intersects the sphere, implicitly define the circle of their intersection.
Your answer must be neat and clear. No points will be awarded for imprecise answers. Your answer
should be in the form of a simple explicit equation that you have drawn a box around...
