Question

how do I integrate:

ln((x+2)/(x+1)) ?

Answer 1

use ln( a/b) = ln(a) - ln(b) to break up the problem

Answer 2

I went from that to the equation I have written above.

Answer 3

why would you combine it to make it harder? phi is right, split it up

Answer 4

integration by parts.
\[\int\limits u dv= u v- \int\limits v du\]
for the 1st integral ln(x+2) dx
u= ln(x+2)
dv = dx

Answer 5

now find du = d/dx ln(x+2) = 1/(x+2) dx
and v = integral dx = x

Answer 6

can you finish?

Answer 7

No I cant
