### What is Meant by Integration by Parts?

In mathematics, integration by parts is a special method of integration when two functions are multiplied together. This method is used when the integrals are difficult to evaluate. In this method, the integration by parts formula moves the product out of the equation, so that the integral can be evaluated easily. The function is of the form: ∫u v dx.
Example: ∫ x lnx dx
By using the integration by parts method, we get
Here, the function is integrated with respect to x, then it becomes
∫ x lnx dx = (½)x2 log x -(x2/4) + C
