How do you differentiate #1 / ln(x)#? Calculus Differentiating Exponential Functions Differentiating Exponential Functions with Calculators 1 Answer Andrea S. Jan 9, 2017 #d/(dx) (1/(lnx)) = -1/(xln(x)^2)# Explanation: Using the chain rule: if #y=ln(x)# and #u=1/y# then: #(du)/(dx) = (du)/(dy)*(dy)/(dx)# So: #d/(dx) (1/(lnx)) = -1/(ln(x)^2)*1/x= -1/(xln(x)^2)# Answer link Related questions How do you use a calculator to find the derivative of #f(x)=e^(x^2)# ?
