Ever wonder how tennis ball manufacturers shape the white rubber strip that holds the ball together? This worksheet gives a plausible hypothesis. Starting from the observation that any parametric curve of the form (cos(a(t))sin(b(t)), sin(a(t))sin(b(t)), cos(b(t))) lies on the unit sphere, the goal is to pick a(t) and b(t) so that the curve looks tennisballesque.
