The question is:
Sketch the region enclosed by the given curves. Decide whether to integrate...
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...
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...
