Help me integrate,
    #5535524 - 04/19/06 09:20 PM (17 years, 9 months ago)

finals are coming up and I just cant grasp some of these integrals. I really didn't expect first year integral calculus would be such a kicker,

Given that S(0 --> 4)e^(x-2)^4 dx=k, find the value of S(0 --> 4)xe^(x-2)^4 dx. Express your answer in terms of the constant k.

and I know this is just Fundamental Theorem but I cant quite get through it fully,
Lim(z-->x) 1/z-x S(x-->z) dt/t+ (t^2+1)^1/2 (or square root)

(S just represents the integral of, going from to...)

I know things like these are hard to actually work out online, but any help would be great. Also if anyone has any worthwhile tricks that are trig sub. oriented it would be great, hah.

Thanks in advance, take care.
