## Homework Statement

Determine

[tex]\int sec(2x) dx[/tex] for interval [tex]\frac{3\pi}{8}[/tex] - [tex]\frac{\pi}{2}[/tex]

## The Attempt at a Solution

I get

[tex]\frac{1}{\pi/2} ln (sec(\frac{\pi}{2}x+tan(\frac{\pi}{2}x))-\frac{1}{3\pi/8} ln (sec(\frac{3\pi}{8}x+tan(\frac{3\pi}{8}x))[/tex]

I am unsure how to simplify this further, wolphram alpha gives a much more elegant
