Hi All,

Does anyone know what I can do to get more precision in the calculation of
inverse trig functions? I keep getting errors when I try to take the acos
of some number like 1.0000007. I think this is the result of imprecision in
an earlier mathematical step to take another arccosine.

Help would be much appreciated!
