Hoe do you differentiate #f(x)=ln(1/x) #? Calculus Differentiating Logarithmic Functions Differentiating Logarithmic Functions with Base e 1 Answer Konstantinos Michailidis Nov 3, 2015 It is #f(x)=ln(1/x)=>d/dxf(x)=(d/dx(1/x))/(1/x)=>f'(x)=-1/x# Remember that if #f(x)=lng(x)# then #f'(x)=(g'(x))/g(x)# Answer link Related questions What is the derivative of #f(x)=ln(g(x))# ?
