Hey guys, I've heard some great things about this website and I was wondering if you guys could give me some help on this problem. My brains about to explode. I tried substitution but to no avail.

This looks very hard leaning towards the impossible.

Where did you get this integral from and what level are you at? If it's part of your working from a bigger question, post the whole question.

[DeegOfPeace]

Thats the whole one :[. I've literally worked on it for hours.

Are you sure those limits are correct?

Which module/ topic is this on?

[DeegOfPeace]

Actually, the question is asking for y'x

thanks guys

UPDATE*** the e^(3x) should be an e^(3t).

I'm also finding y'. I'll be working on this, if anyone has any input it would be greatly apreciated

Hang on, are you saying that y(x) is the result of the integral (in terms of x) and you just need to work out y'(x) i.e. dy/dx?

Because in that case, you shouldn't be trying to evaluate the integral at all, you should be using Leibniz' rule for differentiating an integral!
