Function
Secant Sec (X) = 1/ Cos (X)
Cosecant Cosec (X) = 1/Sin(X)

Cotangent Cotan (X) = 1/Tin(X)
Inverse sine Arcsin (X) = Atn (X/Sqr (–X * X + 1))
Inverse Arccos (X) = Atn (–X/Sqr (–X*X+1))+2* Atn (1)
cosine
Inverse Arccosec (X) = Atn (X/Sqr (X * X–1)) +Sgn ((X)–1)* (2*Atn(1))

secant Arccosec (X) = Atn (X/Sqr (X * X–1)) +(Sgn (X)–1)* (2*Atn(1))
Inverse Arccotan (X) = Atn (X) + 2* Atn (1)
cosecant
Inverse HSin (X) = (Exp (X) – Exp (–X)/2

cotangent HCos (X) = (Exp (X) + Exp (–X))/2
Hyperbolic
HTan (X) = (Exp (X)–Exp (–X))/ (Exp (X)+Exp(–X))
sine
HSec (X) = 2/ (Exp (X) + Exp (–X))
Hyperbolic
cosine
