Implementing a lookup table would most likely be the most efficient method.

If high accuracy is an objective, you should code your own library function using power series, see List of mathematical series - Wikipedia, the free encyclopedia

Although the expression looks complicated at first sight, it reduces to a rather handy recursive form.
