Does anyone know of a good, preferably flash or html-based antiderivative calculator? I'm on a Mac and can't run any windows executable file.(adsbygoogle = window.adsbygoogle || []).push({});

And if not, would someone please tell me the antiderivative of tan?

[edit]

I'll just give the problem I'm working on. I'm trying to find the integral.

[tex]

\int_{0}^{\pi/4}\frac{1 + \cos^2\theta}{\cos^2\theta}d\theta

[/tex]

Subbing in [tex]\sin^2\theta[/tex] for [tex]1 + \cos^2\theta[/tex], I get [tex]\int_{0}^{\pi/4}\frac{\sin^2\theta}{\cos^2\theta}d\theta[/tex] , which I simplified to [tex]\int_{0}^{\pi/4}\tan\theta d\theta[/tex]

Assuming I'm correct up to this point, all I need is the antiderivative of tangent to complete the problem.
