So scrap Math.pow and just use conventional A \* A, and when you say precalc radian to degree should that be put into a var PI = and then just call it when needed?  
was considering just radians throughout as I think the servo control board can input radians.  
@hotNipi Yeah its probably not needed to be fair the only reason I was going to covert it was to reduce the number length, but if it's going to have a negative effect on processing time them maybe leave it, but at least I know how to do it now.
