    55This should at least double the performance for a slightly smaller error (3.576deg vs 4.5deg) term or give slightly faster performance for a sub 0.5 deg error term.

     7The algorithm currently used in the SIN and COS approximation is very accurate but very slow. I propose to improve this with a CORDIC algorithm as well.  For slightly worse accuracy the performance would be about double.
