Re: Evaluate this integral

Look again at the second of the two integrals, I think that you've lost a negative sign. And yes, if the question asks for the answer to be given as an improper fraction then that is what you should do.

Re: Evaluate this integral

ok so it should be (0 - (3(4))/2) + **(-**9/2 - 0) = 6+ (-9/2) which is 1.5 positive sign ==> 3/2. Do you agree?

Re: Evaluate this integral

No, now you've lost a negative sign from the first integral.

(0 - (3(4))/2) + **(-9/2 - 0) = -6+ (-9/2) which is -10.5 or -21/2 ? right?**
