Arm provides a library titled FastMathFunctions that contains single-precision floating-point sin() and cos() functions. These functions use lookup table-based methods to approximate the functions with lookup tables of size 2 KB. Arm also provides a sincos function that computes both the sin() and cos() simultaneously in ControllerFunctions as well. These functions were benchmarked and the results are shared at the end of this section.
