## Homework Statement

Improper Integral of theta/cos^2 theta

## Homework Equations

## The Attempt at a Solution

Hi all, this was one of the few questions on my final today that I just didn't know how to do. I know how to do trig sub, know all my trig identities and know improper integration, but was a bit at a loss for this one.

I could use a half angle for the denominator --> theta / 1/2 [1 + cos(2 theta)] -->

Maybe integrate, and get theta^2 / 1/2 theta + 1/2(sin 2 theta).

I'm sure what I tried was very wrong, but I wanted to make some kind of attempt.

Edit: nevermind, you can't integrate like that.
