Hello
ln ( (e^x+1) / (x^3 + x^2) ) needs to be verified
So here's what I got:
= ln ( (e^x+1) / (x^3 + x^2) )
= ln (e^x+1) - ln (x^3 + x^2)
= (x+1) ln e - ln ((x^2(x+1))
-can't get past this point.
What do you mean by "verified?"
We can go a few more steps:
$\displaystyle = (x+1) ln(e) - ln (x^2(x+1)) $
$\displaystyle = (x+1) ln(e) - ln (x^2) - ln(x+1) $
$\displaystyle = (x+1) ln(e) - 2ln (x) - ln(x+1) $
and since $\displaystyle ln(e) = 1$,
$\displaystyle = (x+1) - 2ln (x) - ln(x+1) $
