Integration by parts is a method to find the product of functions, for example, x sinx, x cosx, x lnx, etc. Generally, this integration occurs when two or more functions are products of each other and can also solve definite (with upper and lower limits) and indefinite integrals. It is the reverse product rule for derivatives. The method used in this is named ILATE. By using this rule, you can determine which one is the first function and which is the second function in the given product.
In this rule;
$$ \text{I stands for inverse function.} $$ $$ \text{L stands for logarithm function.} $$ $$ \text{A stands for algebraic function.} $$ $$ \text{T stands for trigonometric function.} $$ $$ \text{E stands for exponential function.} $$
If we solve the function x ln x, in which x is an algebraic function or logarithmic function, we select which function is first and second by this rule.
In other words;
The integral of the two multiplied functions is the first function × integral of the second function - the integral of the derivative of the first function and × integral of the second function.
Mathematically:
$$ \int u.v \, dx \, = \, u \int v \, dx \, - \, \int [\frac{du}{dx} \, (\int v \, dx)] \,dx $$
u = first function of a variable x. br v = second function of a variable x.
To evaluate an integral using the integration by parts method, follow these steps:
Example:
Solve the function using the by-parts method.
$$ \int x \, sinx $$
Solution:
$$ I \, = \, \int x \, sinx \, dx $$ $$ \text{Take the place of the function by using the ILATE rule:} $$ $$ u \, = \, \text{and} \, v \, = \, sinx \; \text{so that,} $$ $$ I \, = \, \int u.v \, dx $$ $$ \text{Now, using the by-parts rule, we have;} $$ $$ I \, = \, x \int sinx \, dx \, - \, \int[\frac{d}{dx} x(\int sinx \, dx) \, dx $$ $$ I \, = \, x(- \, cosx) \, - \, \int 1.(- \, cosx) \, dx $$ $$ \text{Again integrate;} $$ $$ I \, = \, - \, x.cosx \, + \, \int cosx \, dx $$ $$ \text{Now simplify to get accurate results.} $$ $$ I \, = \, - \, x.cosx \, + \, sinx $$
Example:
Solve the integral of:
$$ I \, = \, \int x^4 \, lnx \, dx $$
Solution:
$$ \text{Take the place of the functions by using ILATE rule.} $$ $$ u \, = \, lnx \; \text{and} \; v \, = \, x^4 $$ $$ \text{Now, using by parts method, we have;} $$ $$ I \, = \, \frac{x^5 \, lnx}{5} \, - \, \int \frac{x^5}{5x} \, dx $$ $$ I \, = \, \frac{x^5 \, lnx}{5} \, - \, \frac{1}{5} \, \int x^4 \, dx $$ $$ \text{Now simplify to get the result;} $$ $$ I \, = \, \frac{x^5 \, lnx}{5} \, - \, \frac{1}{5} \, \biggr( \frac{x^5}{5} \biggr) + c $$ $$ I \, = \, \frac{x^5 \, lnx}{5} \, - \, \frac{x^5}{25} \, + \, c $$
The integral calculator by parts operates by automating the step-by-step process of solving integrals using the integration by parts method, a fundamental technique in calculus. It begins by allowing the user to input the integral they want to evaluate. Behind the scenes, the calculator identifies which part of the integrand is "u" and which is "dv." It then computes the derivative of "u" and the integral of "dv." Next, it applies the integration by parts formula, subtracting the product of "u" and "v" from the integral of "vdu." This step repeats until the integral becomes simplified or the user stops. Throughout the process, the calculator keeps track of constants and integrates them. The final result is provided to the user, frequently with a detailed breakdown of each step to arrive at the solution, assisting comprehension and learning. This tool is invaluable for students and professionals seeking efficient and accurate solutions to complex integration problems.

The integration by parts rule is used to integrate the product of two functions. It involves breaking down the integrals of this product into two parts, one of which is differentiated and the other integrated. The rule is commonly expressed as:
$$ \int u \, dv \, = \, uv \, - \, \int v \, du $$
$$ I \, = \, \int 1.lnx \, dx $$ $$ I \, = \, lnx. \int 1 \, dx \, - \, \int [\frac{d}{dx} \, lnx] \, .1 \, dx $$ $$ I \, = \, x \, lnx \, - \, x $$
