# Integration by Partial Fractions Calculator

Want to get the solution of partial fractions but find it hard to solve? No worries as our integration by partial fractions Calculator is here to solve the problems for you.

## Introduction to Integration by Partial Fractions Calculator

The partial integration calculator is a free online tool that is used to find integral problems of rational algebraic expression. It evaluates the antiderivative function where the degree of the numerator is higher than the degree of the denominator expression.

An Integration by Partial Fractions Calculator is a tool designed to assist in the process of integrating rational functions by decomposing them into simpler fractions. This technique, known as integration by partial fractions, is commonly employed in calculus when integrating functions that are expressed as a ratio of polynomials.

Our Calculator is a valuable tool for solving integrals involving rational functions. By automating the process of decomposition and integration, it enhances efficiency, accuracy, and understanding of calculus concepts. Additionally, after decomposing a rational function into partial fractions, you may also use our u-sub calculator to simplify the resulting integrals further. Our calculator also provides a solution of the complex integral using the u-substitution method. You do not need to do lengthy calculations while calculating these types of integral questions in no time.

## What is Integration by Fraction?

It is an integration technique that uses the partial fraction decomposition method to simplify integrand for the evaluation of a given problem through standard integral rules.

Integration by partial fractions is a method used to break down a complex rational function into simpler fractions, making it easier to integrate each part individually. It's particularly useful when dealing with integrals involving rational functions that cannot be integrated directly using basic integration rules.

Additionally, if you would like to find the solution to integral problems that cannot be solved by any other method of integration, you can use our trig substitution calculator. Our calculator also help you solve integrals more efficiently and accurately. It serves as a valuable tool for students and professionals working in calculus and related fields where such integrals are encountered frequently.

The equation x2 + bx + c cannot be factorized further.

## Evaluation Process of Partial Integration Calculator

The partial integral calculator evaluates the integral problem that has a rational expression like p(x)/q(x) fraction. This calculator checks the nature of a given antiderivative problem, according to the given problem the same partial fraction form is used.

Then the partial fraction integration calculator can factorize the denominator i.e q(x), and equate the numerator. To find the value of A, B, C, etc different methods are used like comparing the coefficient method or equation coefficient of A, B… to zero to get the value of the variable.

After knowing the value of A, B, C etc the integration by partial fractions calculator adds to the decomposition of the partial fractions.

Now the integrand is in the form of the sum of simpler rational functions including constant values of A, B, C, etc. The partial fraction integral calculator solves this rational function using rules of integration and gives the solution of your integral problem easily. Further, If you encounter integrals beyond the scope of partial fraction decomposition, you can utilize our convergent divergent integral calculator for solving integrals with improper or infinite bounds.

Let us examine an example of a partial fraction function to know how this integral partial fraction calculator works.

## Example of Integration by Partial Fraction

Partial Fraction can be found by the integration by partial fractions calculator but it is also important to do manual calculations. Here is an example of manual calculation,

### Example:

Integrate the following:

$$\int \frac{1}{x^2 - 4} dx$$

Solution:

$$\int \frac{1}{x^2 - 4} dx \;=\; \int \frac{1}{(x+2)(x-2)} dx$$

$$\int \biggr( \frac{A}{x+2} + \frac{B}{x-2} \biggr) dx$$

$$Let\;x\;=\; -2 ; \;A(-4) + \;B(0) \;=\; 1 \to \;A\; =\; -\frac{1}{4}$$

$$Let\;x\;=\;2 ; \;A(0) + B(4) \;=\; 1 \to \;B\;=\; \frac{1}{4}$$

$$\int \biggr( \frac{-\frac{1}{4}}{x+2} + \frac{\frac{1}{4}}{x-2} \biggr) dx$$

$$\int \biggr( - (\frac{1}{4}) \frac{1}{x+2} + (\frac{1}{4}) \frac{1}{x-2} \biggr)$$

$$\frac{1}{4} ln | x+2 | + \frac{1}{4} ln |x-2| + C$$

$$\frac{1}{4} \biggr( ln |x-2| - ln |x+2| \biggr) + C$$

$$\frac{1}{4} ln \frac{|x-2|}{|x+2|} + C$$

Thus it is the final solution of our function with specific limits. If you would like to solve definite integral problems of numerical analysis, you can you our simpson error calculator.
