Try substituting x+1 = u
dx= du
So basically you need to integrate 1/u^2
-after integrating substitute u by x+1
-then put the limits
Question is to evaluate by partial fractions
my attempt
giving coefficients as
and so the original integral is equal to
I think i'm tripping up here on the 2nd integral
I had
But I don't think this is right. Can someone show me how to integrate the 2nd integral? Thanks.
