Derivative of a x proof

Web3.4. Duplication Operation. We will now take derivative of x3 with respect to x in a way that is excessively complicated but illustrates the subtleties in the chain rule. We break down f(x) = x3 as f = g h where h(x) = (x;x;x) and g(x;y;z) = xyz. The derivative of h is a function R1!R3 and is 7!( ; ;) , represented as a row vector (1;1;1) in WebTo find the derivative of 1/x, we can write it as 1/x = x -1. Then by the power rule, its derivative is -1x -2 (or) -1/x 2. How to Prove that the Derivative of ln x is 1/x? We can prove that the derivative of ln x is 1/x either by using the definition of the derivative (first principle) or by using implicit differentiation.
