What is the Integration by Parts?
Integration by parts is defined as the method of integration used when two different functions are multiplied. It is used when the integrals are difficult to evaluate from the substitution method.
Integration by parts is often used to integrate products of functions involving polynomials, exponential functions, logarithmic functions, trigonometric functions, and other types of functions. It is a fundamental technique in calculus and is widely applied in various fields such as mathematics, physics, engineering, and economics.
Additionally, Integration by parts is a used in calculus to evaluate the integral of a product of two functions. Further, if you would like to find the solution of integral problems that cannot be solved by any other method of integration. you can use our trigonometric substitution calculator.

Formula used by Integral by Parts Calculator:
The formula of integration by parts used by integration by parts calculator contains functions. Integration by parts formula has two product functions.
$$ \int u.v dx \;=\; u \int v dx - \int \Biggr[\frac{du}{dx} \Biggr(\int v dx \Biggr) \Biggr] dx $$
where,
u is the first function
v is the second function.
dx is the integration variable.
In this formula, we select one function, u to be differentiated and the other function, v, to be integrated. By applying the integration by parts formula, the original integral is transformed into a simpler form that can be more easily evaluated.
Additionally, For assistance with selecting appropriate functions u and v, you can utilize our u substitution integration calculator. This tool helps simplify integrals by substituting variables and functions, making complex integrals more manageable.
How Does an Integrate By Parts Calculator Work?
The integration by parts solver is simply designed to give complex problem results related to integration by part method. When you enter an integral function in the calculator whether it is definite or indefinite it starts to analyze the given function structure. Based on the problem format we decide whether u is the first function orv is the second function using the ILATE rule for integration by parts.
In ILATE rule inverse, logarithmic, algebraic, trigonometry, exponential function as a first function. After that, it takes the first function integration and treats the second as constant then separates it into a minus sign along with an integral sign as it has first function integration and takes the derivative of the second function as per the formula.
In this way, the calculation is going on till the integral function is reduced to the simplest form with constant C. In the case of definite after integration, it applies the upper and the lower limits respectively.

Example of the Integral By Parts
Now you see an example of a definite integral function,
Example:
$$ \int_{0}^{2} ( xe^x ) dx $$
Solution:
The definite integrals are,
$$ \int_{0}^{2} x e^x dx \;=\; 1 + e^2 \approx 8.3891 $$
The steps are as follows,
First of all, calculate the definite integral,
$$ \int_{0}^{2} e^x xdx $$
For the integrand ex, integrate by parts, ∫fdg = fg - ∫gdf, where
$$ f \;=\; x, dg \;=\; e^x dx $$
$$ df \;=\; dx, g \;=\; e^x $$
$$ e^x x|_{0}^{2} - \int_{0}^{2} e^x dx $$
Evaluate the antiderivative at the limits and subtract,
$$ e^x x \Biggr|_{0}^{2} \;=\; e^2 2 - e^0 0 \;=\; 2e^2 $$
$$ 2e^2 - \int_{0}^{2} e^x dx $$
By applying the fundamental theorem of calculus, the antiderivative of ex,
$$ 2e^2 + (-e^x) \Biggr|_{0}^{2} $$
Evaluating the antiderivative at the limits and subtracting,
$$ (-e^x) \Biggr|_{0}^{2} \;=\; (-e^2) - (-e^0) \;=\; 1 - e^2 $$
So, the answer is,
$$ =\; 1 + e^2 $$
Thus it is the final solution of our function with specific limits. If you would like to solve the indefinite integral of the given solution, you can use our calculator indefinite integral. Our calculator also helps to find the indefinite integral of the indefinite function.
