Well, I'm working on a project, but I've run into a bit of a snag: an antiderivative that I need to evaluate, but can't. Even Mathematica's stuck on this one. :) Here it is:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int \frac{dx}{2+cos(ax)-cos(\frac{b}{x})}[/tex]

Any help would be appreciated, even if a numerical approximation is all that can be found (actually, that would probably be most useful). BTW, a and b are constants. Thanks a bunch!
