Inverse Functions

-----------------------------------

Are there inverse functions in turing? Such as sin-1 or cos-1?

I think that arctand is inverse of tangent... atleat it worked for couple of tries...

you can get inverce sin and cos using those formulas:

arcsind (x) = arctand (sqrt ((x *x) / (1 - (x *x)))) 
arccosd (x) = arctand (sqrt ((1 - (x *x)) / (x *x)))
