New description:
(1) Description for "arcsin" wrongly says it is "The inverse of the
hyperbolic sine function" !!
{{{
arcsin?
File: /home/golam/foo/sage-4.0.1/local/lib/python2.5/site-
packages/sage/functions/trig.py
Type: <class 'sage.functions.trig.Function_arcsin'>
Definition: arcsin(x, hold='False')
Docstring:
The inverse of the hyperbolic sine function.
EXAMPLES::
sage: arcsinh(0.5)
0.481211825059603
sage: arcsinh(1/2)
arcsinh(1/2)
sage: arcsinh(1 + 1.0*I)
}}}
(2) Is it also missing " ginac='acos' " in conversion dict?
Both "arccos" and "arctan" have that conversion defined.
