1. Integral Help
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.

2. Re: Integral Help
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.
3. Re: Integral Help
Thats the whole one :[. I've literally worked on it for hours.
4. Re: Integral Help
Are you sure those limits are correct?

Which module/ topic is this on?
5. Re: Integral Help
Actually, the question is asking for y'x

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!
