That $c^2 = 2$ gives an exceptionally well-behaved situation is actually seen just be thinking about secondary-school-level trigonometry. It's striking how a little trigonometry problem leads straight into moderately exotic (by comparison to this sort of trigonometry) functions, but I suppose the same can be said of other things that we've all seen. I'm going to print out the two answers posted so far and think about them before saying much more. | |
