The following is a list of nonintrinsic math functions that can be derived from the intrinsic math functions:

FunctionDerived equivalents
SecantSec(X) = 1 / Cos(X)
CosecantCosec(X) = 1 / Sin(X)
CotangentCotan(X) = 1 / Tan(X)
Inverse SineArcsin(X) = Atn(X / Sqr(-X * X + 1))
Inverse CosineArccos(X) = Atn(-X / Sqr(-X * X + 1)) + 2 * Atn(1)
Inverse SecantArcsec(X) = Atn(X / Sqr(X * X - 1)) + Sgn((X) - 1) * (2 * Atn(1))
Inverse CosecantArccosec(X) = Atn(X / Sqr(X * X - 1)) + (Sgn(X) - 1) * (2 * Atn(1))
