I know I have to know it, but somehow I have difficulty with solving the logarithmic equations. In the script, I found one and can't go further. I would be glad if someone could just write me the between steps, how to come from this equation:
$\frac{1}{(\frac{1}{F(E2)}-1)*e^{\frac{E1-E2}{kT}}+1}$
to this equation
$\frac{1}{e^\frac{E1-E2 + kT*ln[(\frac{1}{F(E2)}-1)]}{kT}+1}$
