An evil math problem.

Daaaugh, you figured it out... I knew should've changed the top sec^2(sec^-1 x) to something that doesn't cancel out XD

No, I didn't render it in LaTeX, though I could have. I just took the lazy route and did it in Microsoft formula editor.

ChaosMageX rocks doubly for solving and using LaTeX. Awesome, epic points.

LOL it\'s THE pancake rule hehe

I like his math. It's delicious! :9

I love when I see a math problem in a web comic and someone in the comments has solved it. Some faith in humanity restores itself.

Dammit! I hate it when artists put math problems in their comics because it makes me want to solve them. XP Anyway, it's not an evil math problem because it simplifies. This is the solution in LaTeX: \int_{\sqrt{2}}^2\frac{(\sec(\sec^{-1}x))^2}{x\sqrt{x^2-1}}dx = \int_{\sqrt{2}}^2\frac{x^2}{x\sqrt{x^2-1}}dx = \int_{\sqrt{2}}^2\frac{x}{\sqrt{x^2-1}}dx = \sqrt{x^2-1}\bigg|_{\sqrt{2}}^2 = \sqrt{2^2-1} - \sqrt{\sqrt{2}^2-1} = \boxed{\sqrt{3} - 1} It should be able to compile with the standard amsmath and mathtools packages. Did you use LaTeX to create the image of the problem that's pictured in this comic?
