so far i have:

i let

change the limits from x=5 to u=24, x=-1 to u=0

and have

which gives me -1.788 but that isn't any of the answers provided! (Headbang)

i don't know what i am doing wrong with this portion of the problem:

i keep getting by antiderving cos

and when i evaluate that between -1 and 5

i get -.9056 which when added to 1.5 isn't correct. could you guide me as to where i went awry? thanks. =/ - January 4th 2009, 09:52 PMmr fantastic
I have already told you in my earlier reply that cannot be found in terms of a finite number of elementary functions. I don't know why you're insisting on trying to integrate it.

.... if you bother to differentiate (using the chain rule) you will quickly realise this.
