How to Calculate Integration By Parts of an Expression?
In mathematics, integration by parts is a special method of integration when two functions are multiplied. The following are the steps that help you in solving the different integrals. Follow them to do the integration of an expression manually
- Take any function in the form of ∫u v dx. Where u and v are the two different functions
- The formula to calculate these types of functions using integration by parts method is ∫u⋅dv=u⋅v−∫v⋅du
- Identify u and v functions in your expression and substitute them in the formula
- First calculate Integration of dv to obtain v
- Then, calculate integration v with respect to v.
- Replace the obtained values in the formula to get the solution.
Example
Question: Solve ∫x. cos(x) dx by using integration by parts method?
Solution:
Given that,
∫x. cos(x) dx
The formula of integration by parts is ∫u⋅dv=u⋅v−∫v⋅du
So, u=x
du=dx
dv=cos(x)
∫cos(x) dx= sin(x)
By substituting the values in the formula
∫x. cos(x) dx= x.sin(x)-∫sin(x) dx
=x.sin(x)+cos(x)
Therefore ∫x. cos(x) dx=x.sin(x)+cos(x)+C

FAQs on Integration By Parts Calculator
1. How is the product rule related to integration by parts?
From the product rule, we can get the integration by parts formula. It is used when integrating the product of two expressions.
2. How do you calculate integration by parts?
The formula to calculate integration of any product expression by using integration by parts method is ∫u⋅dv=u⋅v−∫v⋅du. The formula replaces one integral with another. It means the one on the right is simpler to evaluate.
3. What is the goal of integration by parts?
The main goal of integration by parts method is to replace a difficult integral with one that is easier to evaluate.
4. Compute ∫ x lnx dx by using integration by parts process?
Integration by parts formula is ∫u⋅dv=u⋅v−∫v⋅du
From that u=x, du=dx
dv=logx, ∫ logx dx=x(log(x)-1)+C
∫ logx dx= xlog(x)-x+C
∫ x lnx dx= (½)x2 log x - (x2/4) + C
