    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.

    Re: Integration of trigonometric functions

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

    Do you know how to evaluate this?

    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

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

    Thank you
