1. ## Finding Derivatives

f(x)= (lnx)/(1-e^x)

Its got me stumped, I understand the basics of deriving the simpler versions of these. lnx=1/x but, I am having problems with coming up with the solution for this.

2. You have to apply the Quotient Rule:

$\left[ {\frac{{f(x)}}
{{g(x)}}} \right]' = \frac{{f'(x) \cdot g(x) - f(x) \cdot g'(x)}}
{{g^2 (x)}}.$
