# Math Help - So Confused!

1. ## So Confused!

Confused! I hate finding the antiderivatives of cos/sec/sin, etc!!!!!

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the region.

Hint: If you've forgotten that you know an antiderivative for , consult the integral table on the back cover of your text.

it is better to integrate it with respect to x..

thus, the equation is:

$\displaystyle\int_{\frac{-\pi}{4}}^{\frac{\pi}{4}} \left[ {(4\sec x)^2 - 7\cos x} \right] \, dx$
