For the purpose of my class, "math unlimited" (see download section), I can't use the built-in atan() function. Instead, I have to program it myself, using an infinite series.
The problem is, the series I find in books only works for arguments <= 1. That is, it will only work if the resulting angle has an absolute value of <= 45 degrees. And for arguments approaching 1, the infinite series will converge very slow.
Does anyone know of a conversion function, to reduce, for instance, atan(2) to an atan() of smaller angles?
And, does anybody know conversion functions, or infinite series, to obtain asin() and acos()?
