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 far as 5 int. tan^-1(x), and I get 450 once I plug in the limits, Am I missing anything?
