Hint: Here we will first form the integral equation in such a way that we can apply the integration by parts. Then we will use the formula of the integration by parts and simplify the equation to get the integration of the required equation.
Complete step by step solution:
Given function is .
We can write the above equation as
Now we will use the basic formula of the integration by parts i.e. . Therefore by applying this we get
We know that the differentiation of the is equal to i.e. . Therefore by putting this value in the equation, we get
Now by using the simple integration we will get the simplified equation. Therefore, we get
Now we will substitute and by differentiating it we get . From this we will get the value of i.e. . Therefore, the equation becomes
Now by using the simple integration we will get the simplified form of the above equation. Therefore, we get
Adding and subtracting the terms, we get
Now we will open the brackets in the equation. Therefore, we get
Substituting the value of in the equation, we get
Hence the value of the given integration is equal to .
Note:
Integration is defined as the summation of all the discrete data. Differentiation is the opposite of integration i.e. differentiation of the integration is equal to the value of the function or vice versa. Here we should note that we need to convert the given integrand such that we can apply a suitable integration formula. We should know the basic formula of the integration by parts of an equation to solve this question. We must not forget to put the constant term after the integration of an equation.
