As you have solved b you must have already computed |S|. From having that expression you should be able to progress.

Where the magnitude of S is 1, what does that look like mathematically in terms of x y and z? In other words, you have a locus of points, and all of these points, when you calculate the magnitude of S there, it's equal to 1. What does this look like mathematically?
