Hello I've attached a question with the working I've done so far. I'd really appreciate it if someone can tell me if I've approached the problem correctly.

Thank you.

Hi Furyan! :)

Yep. You approached the problem correctly.

The only thing missing is that you didn't handle the integral boundaries yet.

You appear to have dropped them.

So you should have:

$\displaystyle (-e^{\cos x + 1}) |_0^{\pi/2}$

Do you know how to evaluate this? - Dec 18th 2011, 09:17 AMFuryanRe: Integration of trigonometric functions
Hi ILikeSerena

Thank you!:)

It was the integration I wasn't sure about so I just left the limits out, but I shouldn't get in the habit of doing that.

I can evaluate

$\displaystyle (-e^{\cos x + 1}) |_0^{\pi/2}$

Thank you
