Abstract
This study proposes a technique for approximating high-cost calculations at low cost in embedded systems. Fast calculation of arctangent (as given by atan2) was developed by the proposed technique. Relative to the atan2 standard library function, the resulting approximation is 20 times as fast and requires only one-third the memory.
