    Use the substition u = cos1/2 x

    You're welcome

    you are kidding aren't you? It's not homework, i'm choosing to do it. and i've been looking at it for 20 minutes and didn't get anywhere- tried using the addition formulae and it wasn't working- so yes, i already have 'put in'

    Use the substitution given do some C4 maths, things will cancel

    Whether or not it's homework is irrelevant. Show us your working, we can't help you unless you show or at least tell us what you've done. You've said you've used the sub, what exactly have you tried? Show.
