I can get behind this; hyperbolic geometry isn't particularly common.

I agree for removing pow, but not for deg and rad. Yes, it's trivially
done, but having it defined in the library does make the code more
readable and saves having to memorize the formulas (which are simple
but using it in-place doesn't help readability at all).
