 Hello and welcome to the session. I am Deepika here. Let's discuss a question which says integrate the holding function x log x. Let us first understand the method integration by parts which is useful in integrating products of function. So if we have two functions fx and gx then the integral of fx gx is equal to fx into integral of gx minus integral of gx. The integral of the product of two functions is equal to first function into integral of the second function minus integral of differential coefficient of the first function into integral of the second function. So this is a key idea behind that question. Let's help up this key idea to solve the above question. So let's start the solution. Integrate x log x. Whenever there is a logarithm function we take it as a first function. So integral of x log x. Now first function is log x is equal to log x that is first function into integral of the second function. That function integral of the second function that is x dx is equal to log x into integral of log x is equal to x squared by 2 log x upon 2 log x minus. And the answer for the other question is 2 log x minus x squared by 4 plus c solution is clear to you. Bye and take care.
