Inverse of trigonometric functions?
1 point by tc-rucho 5662 days ago | 1 comment
It's well known that sin, cos and tan have been added in arc3, but what about the inverse of these funcitons?

I know the patch is trivial, but if sin, cos and tan are there, these functions definitely must be there too.

They're in the latest arc3.tar.
