Small thing I noticed when plotting functions: since tangent and hyperbolic sine look very similar to arkus sine (inverse of sine), plotting tan(sin(x)) and sinh(sin(x)) gives you a weird approximation of a perfectly straight triangle wave that you (logically) get when you plot asin(sin(x)). If you average the both approximations, you get even a more accurate one.

EDIT: I wonder what this weird almost triangle wave sounds like.
