If u(x) and v(x) are any two differentiable functions of a single variable y. Then, by the product rule of differentiation, we get; u’ is the derivative of u and v’ is the derivative of v. To find the value of ∫vu′dx, we need to find the antiderivative of v’, present in the original integral ∫uv′dx. Note: 1. Integration by parts is not applicable for functions s… Q.1: Find ∫ x cos x Solution: Given, ∫ x cos x The integrand here is the product of two functions. Therefore, we have to apply the formula of integration by parts. As per the formula, we have to consider, dv/dx as one function and u as another function. Here, let x is equal to u, so that after …

So the integration by parts formula can be written as: ∫ u v d x = u d x − ∫ ( d u d x ∫ v d x) d x. There are two more methods that we can use to perform the integration apart from the integration by parts formula,. They are: The method of Integration by Substitution. The method of Integration using Partial Fractions.

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)]”

Integration by Parts is a special method of integration that is often useful when two functions are multiplied together, but is also helpful in other ways. You will see plenty of examples soon, but first let us see the rule: ∫ u v dx = u ∫ v dx − ∫ u' (∫ v dx) dx. u is the function u(x) v is the function v(x) u' is the derivative of the function u(x)

Formula for Integration by Parts If u and v are two functions of x, then the formula for integration by parts is – ∫ u.v dx = u ∫ v dx – ∫ [ d u d x. ∫ v dx]dx i.e The integral of the product of two functions = (first function) × (Integral of Second function) – Integral of { (Diff. of first function) × (Integral of Second function)}

Integration by parts is used to integrate products of functions. In general it will be an effective method if one of those functions gets simpler when it is differentiated and the other does not get more complicated when it is integrated. For example, it can be used to integrate x.cos(x).
