    got like 11.66 but not checked and owing to some of the numbers I obtained I reckon something went wrong early on; think I got the method though..

    edit: by the method I mean a method.
    LOL. I actually did make a mistake. -_-' I put a postive in a place where a negative should have been so your answer is prob right XD.

    TeeEm, your sub was so much more simplier XD and quicker.

    Edit: got 5.57 after correcting my mistake -.-' lol

    you will be given a substitution in the exam and you will only be expected to do the one with the limits (easier)

    Perhaps you are right...
    in an exam you will be given a substitution

    use 2x = -1 + 4 coshθ

    Solutions in about 20 minutes
    I actually came up with that sub..just don't think I did the rest properly.
    edit: getting something around 9.41 now rather than my answer before
