I don't know about the above, but check out an algorithm called CORDIC. It
provides a set of fixed-point trigonometric functions in an iterative
There are probably other references, I'm giving you the ones I've got
(Article plus references from that article):

Hope this helps a bit. I thought it is quite interesting. This algorithm
can deliver sin, cos, atan, sinh, cosh, atanh, division with nothing more
than a few add, multiply and shift operations.
