Suppose we know vector PQ which is in a plane in space.  We also know angle
theta, which is the angle between PQ and PR.  PR is also in the same plane
as PQ, and the unit length of PQ is the same as PR.  So, given all this,
how do we find vector PR?

In other words, how do we solve for point R in three dimensional space?

Another way to put it is how can one use a polar coordinate system that is
in an arbitrary plane in space?
