The question pretty much says it.
I need to solve $t$ in this equation: $$ x = t - \sin{(t)} $$ Either I've forgotten how to do it, or I am just blind, etc. Anyway, I'm completely stuck at this.
Actually, I need to solve a vector:
$$(\; x \; , \; y \;) = (\; t - \sin{(t)} \; , \; 1 - \cos{(t)} \;)$$
Inverse of $y$ is trivial: $t = \cos^{-1}{(1 - y)}$. But that doesn't help me much further on.
