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))) |
