WebOct 23, 2024 · Derivative of 1/x 3 by First Principle The derivative of a function f (x) by the first principle is given by the following limit formula: d d x ( f ( x)) = lim h → 0 f ( x + h) − f ( x) h Put f (x) = 1/x 3 So the derivative of 1/x 3 from first principle is d d x ( 1 x 3) = lim h → 0 1 ( x + h) 3 − 1 x 3 h WebPractice the following important questions in class 11 Maths Limits and Derivatives that should help you to solve the problems faster with accuracy. Question 1: Find the derivative of the function x 2 cos x. Solution: Given function is x 2 cos x Let y = x 2 cos x Differentiate with respect to x on both sides. Then, we get: dy/dx = (d/dx)x 2 cos x
