What is Chain Rule?
Chain rule is a method to find derivative of Composite Function. It states that the derivative of composite function f(g(x)) is f'(g(x))⋅ g'(x). In other words, Cos(4x), is a composite function and it can be written as f(g(x)) where f(x) = Cos(x) and g(x) = 4x.
We can then compute the derivative of Cos(4x) using the chain rule and the derivatives of Cos(x) and 4x.
Chain Rule: Theorem, Formula and Solved Examples
Chain Rule is a way to find the derivative of composite functions. It is one of the basic rules used in mathematics for solving differential problems. It helps us to find the derivative of composite functions such as (3x2 + 1)4, (sin 4x), e3x, (ln x)2, and others. Only the derivatives of composite functions are found using the chain rule. The famous German scientist, Gottfried Leibniz gave the chain rule in the early 17th century.
