I need some help with evaluating this... I think I've got the integration bit right, but I don't know what to do with the 'n' when evaluating


Thanks! :)

Deal with it like any other exponent in an integral, raise the power, divided by the raised power, sub in limits

I was trying to sub in cosx for u so I was getting confused, but makes sense now :)
you don't sub the function for u after you've already changed the limits in a definite integral
