excellent, got it. Thanks a million.

Hi, here's my problem Use the Fundamental Theorem of Calculus to evaluate the definite integral. from the int. of -1 to 1, with the function being 5/x^2+1 = 5 int. 1/x^2+1 = 5 int. tan^(-1)(x) = 5 x tan^-1(x) Plug in 1 and -1...subtract...= 450, except it's wrong. I've gotten as...

thank you!

I don't understand how to evaluate a fraction in a definite integral, could anyone please explain this problem to me? int. between 3 (lower integral) and 4 (upper integral) of 3x^2+2/x^2 I thought of using the substitution law, and got as far as 1/6 u * du/x ...I don't quite know how to...
