try to expand (x+1)^2 and see what u can do
Hi have the following integral, i have expanded the numerator, and then thinking a change of variable on the denominator but doesnt seem to be working heres, the question:
Evaluate the following integral
(x+1)^2dx/x^2+1 Between the limits of 2 and 0.
Many thanks in advance.
That doesn't mean, though, that we should always blindly resort to substitution. If a method is present, and the OP is taught to ignore it, how will he expect to progress? If he doesn't understand my method, he doesn't have to use my method, but that doesn't mean that the method isn't important and should be completely ignored.
