heres the equation that will converge conditionally: http://img440.imageshack.us/img440/9945/untitled3jg.jpg [Broken]

changes to

An = n/(1 + nLNn)

2. Relevant equations

alternating series equation.

converges conditionally.

d/dn An = (1-n)/(1+nLNn)^2

3. The attempt at a solution

I'm not sure how the first equation changes to the second equation, and then i'm supposed to use l'hopitals rule.

any help please.
