The trig functions should run very fast because they don't rely on factorials or anything but the nth root has iterations of 15*(n-1) so it might run a bit slower but is pretty much the best possible.

Nice work. I did my own version of these a while back aswell :-)

This is based on the Taylor Series but it's interesting to see a different approach
