Best ResponseYou've already chosen the best response.0I think it should be \[\int\limits_{}^{} 1/\sin(x)\cos^2x\]

Best ResponseYou've already chosen the best response.1Or start from \[\int\frac{\sqrt{1+x^{2}}}{x} dx\]

Best ResponseYou've already chosen the best response.0You could started from there, I got up to 1/sinxcos^2x

Best ResponseYou've already chosen the best response.1Assuming that you did the other part correct then.. \[\int \frac{1}{sinxcos^2{x}}\] wait..are you sure about that though?

Best ResponseYou've already chosen the best response.0dw:1342236036378:dw \[\sec \theta = \sqrt{1+ x^2}\] \[\tan \theta = x\] \[\sec^2 \theta d\theta = dx\] \[\int \frac{\sqrt{1+x^2}}{x}dx \implies \frac{\sec \theta(\sec^2 \theta d\theta )}{\tan \theta}\]

Best ResponseYou've already chosen the best response.0I'm sure that \[\int\limits_{}^{} \sec^3x/\tan(x)\]

Best ResponseYou've already chosen the best response.0\[\int \frac{1}{\sin x \cos^2 x}dx \implies \int \csc x \sec^2 x dx\]

Best ResponseYou've already chosen the best response.0That's why I didn't change it to that because I knew there was nothing to do there.
