What is the inverse of the sine function?
-I * log( sqrt(1-x*x) + I * x)
where I is the usual complex root of -1.

As I hinted in the discussion of the Taylor expansion, I used
the symbolic mathematics package Maple
[fixed width font required for below]
maple> convert(arcsin(x),expln);
2 1/2
-I ln((1 - x ) + I x)
If you do heavy-duty symbolic manipulation, then you should
consider Maple. If you do not need the manipulation engine to be
as strong as possible, but you need a lot of programmability, then
you should consider Mathematica. In either case, other newsgroups
are more appropriate for discussions of their relative properties
(e.g., sci.math.symbolic comp.soft-sys.math.mathematica
comp.soft-sys.math.maple )
