How do you differentiate #f(x)=xln(1/x)-lnx/x #? Calculus Differentiating Logarithmic Functions Differentiating Logarithmic Functions with Base e 1 Answer Konstantinos Michailidis Jan 3, 2016 It is #f'(x)=ln(1/x)-1-(1-lnx)/x^2# Explanation: The derivative is #d(f(x))/dx=x'*ln(1/x)+x*ln(1/x)'-((lnx)'x-x'*lnx)/(x^2)=> d(f(x))/dx=ln(1/x)+x*((1/x)'/(1/x))-(1-lnx)/x^2=> d(f(x))/dx=ln(1/x)-1-(1-lnx)/x^2# Remember that #d(lnx)/dx=1/x# Answer link Related questions What is the derivative of #f(x)=ln(g(x))# ?
