![]() ![]() It helps to find integration of a complex function with a direct and easy method. It is known as reverse chain rule or u-substitution or substitution rule. Yes, there is a technique of finding integration by using chain rule in integration. b∫ a f(t) dt = F(b) - F(a) (integration of definite integrals).d / dx x∫ a f(t)dt = f(x) (derivative of indefinite integrals).One rule is to find the derivative of indefinite integrals and the second is to solve definite integrals. To calculate the integration by parts, take f as the first function and g as the second function, then this formula may be pronounced as: The integral of the product of two functions (first function) × (integral of the second function) Integral of (differential coefficient of the first function) × (integral of the second function. The fundamental theorem of calculus defines two rules to solve integration. This rule is also known as the substitution method. ![]() ![]() It is used to solve those integrals in which the function appears with its derivative. The reverse of the chain rule is an integration rule called the substitution rule. There is a chain rule in integration also that is the inverse of chain rule in derivatives. Related: Is Chain Rule same as Product Rule? - Difference & Comparison FAQ’s Does Chain Rule exist in Integration? It calculates the antiderivative of a function by using its derivative. It calculates the rate of change of a function with respect to another function. The reverse chain rule formula for a function Suppose for a function y = fgx the chain rule formula can be written as, This rule can also be called the “substitution Rule", or the “U-Substitution Rule". The reverse chain rule combines these two parts of the function and integrates it directly. We can do the reverse of chain rule to integrate complicated functions where the function and its derivative appear in a combined form. It is a technique that allows us to find derivatives. Since the chain rule is used for derivatives to calculate derivative of complex functions or the function in combination form. The reverse chain rule is a technique of finding integration of a function whose derivative is multiplied with it. This article will help you to understand the reverse chain rule and the difference between the chain rule in derivative and integration. Same as derivatives, there is a chain rule in integration known as the reverse chain rule. In derivatives, we have a chain rule to evaluate derivatives of complex functions.

Introduction $y$, then $f(x(t),y(t))$ is a differentiable function of $t$.
