d dx ln x The derivative of ln x is 1 x i e d dx ln x 1 x In other words the derivative of the natural logarithm of x is 1 x But how to prove this Before proving the derivative of ln x to be 1 x let us prove this roughly by using its graph For this we graph the function f x ln x first
A fundamentally import calculus result is that d dxe x e x Let y lnx x e y Differentiate wrt y dx dy e y using above result dx dy x dy dx 1 x By the chain rule Answer link D ln x dx Have a question about using Wolfram Alpha Compute answers using Wolfram s breakthrough technology knowledgebase relied on by millions of students professionals For math science nutrition history geography engineering

Enter the function you want to find the derivative of in the editor The Derivative Calculator supports solving first second fourth derivatives as well as implicit differentiation and finding the zeros roots You can also get a better visual and understanding of If you can use the chain rule and the fact that the derivative of e x is e x and the fact that ln x is differentiable then we have frac mathrm d mathrm d x x 1 frac mathrm d mathrm d x e ln x e ln x frac mathrm d mathrm d x ln x 1 e ln x frac mathrm d mathrm d x ln x 1
Derivative of natural log of x with respect to x is 1 x Let s find derivative of ln x by using first principle implicit differentiation and others Here we have also covered some examples related to it The derivative of the logarithmic function y ln x is given by d dx ln x 1 x You will see it written in a few other ways as well The following are equivalent d dx log ex 1 x If y ln x then dy dx 1 x We now show where the formula for the derivative of log e x comes from using first principles Proof of formula
