I think someone coming from a calculus background should not be
discouraged from those habits of thought. They're useful in calculus.
There's definitely an "if frequency > delta then |360 - v| < epsilon"

The polyhedron starts out looking spherical (round anyway) and gets
more and more spherical. Clearly it's not approaching "perfect
flatness" *at all* as f increases. It just gets more smoothly
rounded, like a bowling ball (but under the microscope, we see
