Hi i am sorry if this is a stupid question but is there a taylor approximation to the function f = $\displaystyle ln(1-e^{-x})$ thanks

Yes
but $\displaystyle ln(1-e^{-x}) = f(a) + f'(a)(x-a) +.....$ the first term $\displaystyle f(a)$ is $\displaystyle ln(0)$ which is undefined
Then try centering the series on something other than 0.
