# Evaluate the definite integral

## Homework Statement

$\int^{\frac{\pi}{4}}_{0}\frac{1+cos^{2}(x)}{cos^{2}(x)}$

## The Attempt at a Solution

I tried u-sub, splitting it up into 2 fractions, and a trig identity (cos^2x=(1+cos2x)/2).
Am i missing something? The other problems were quite easy.

What did you get if you split it up in two fractions? Why didn't it work?

I got two fractions, 1/cos^2(x) and cos^2(x)/cos^2(x)=1

I wasn't sure how to integrate the 1/cos^2(x)

Wow, see what happens when I take a summer off?
Thanks a lot.
