As I do not know anyone fresh enough with Calculus, certainly this forum (that I just joined) is my best destination.

I studied calculus nearly ~20+ years ago. I nearly forgot everything...

Here is my problem

After a few manipulations the integrand I'm dealing with comes out as product of two functions which are (independently) the derivative of the denominator logarithm.

That means (being D=d/dx):

Dln(x+1) = [1/(x+1)]

Dln(x+2) = [1/(x+2)]

The integral I'm trying to resolve is:

(integral of) [1/(x+1)] * [1/(x+2)] dx

I’m now stuck because I cannot recall at all how to find the primitive, i.e. how to resolve the integral. I believe it should be resolved integrating by parts. Right?

Could someone please guide me through?
