Introduction to Long Division Integral Calculator:
The long division integral calculator is a great online tool that can simplify the process of integrating rational functions. This tool helps in evaluating polynomials where the numerator polynomial is greater than or equal to the degree of the denominator polynomial.
It is a helpful tool as it allows you to get accurate results for students and professionals who need to complete daily tasks in mathematics and related fields.
What is the Long Division Integral?
Long division integral is a method in calculus that is used to divide the numerator polynomial by the denominator polynomial to simplify the given expression to integrate it easily. The process results in a quotient and a remainder, allowing the integral of a complex rational function to be broken down into simpler parts.
There is another method called partial fraction that is used to solve these rational function problems but for complex rational integral functions this process is suitable to simplify the integration method.
How to Integrate Using Long Division?
Long division in integration simplifies the process of integrating rational functions by breaking them down into simpler ones. Let us see an example of long-division integration Here are the steps to follow:
Example: Integrate the following:
$$ \frac{x^3 + 2x^2 + x + 1}{x^2 + 1} $$
Solution:
Step 1:
Write the numerator polynomial inside the long division symbol and the denominator polynomial outside.
$$ x^2 + 1 \sqrt{x^3 + 2x^2 + x + 1} $$
Step 2:
Divide the leading term of the numerator by the leading term of the denominator to get the first term of the quotient by multiplying the entire denominator with this term, and subtracting the result from the numerator.
\begin{array}{rrrrrrr} x + 2 \\[-3pt] x^2 + 1 \enclose{longdiv}{x^3+ 2x^2 + x + 1} \\[-3pt] \underline{-x^3 \; \; \; \; \; \; \; \; \; \; \pm x\; \; \; \; \;}\phantom{2} \\[-3pt] 2x^2 \; \; \; \; \; \; \; \; \; + 1 \\[-3pt] \underline{-2x^2\; \; \; \; \; \; \; \; \; \pm 2} \\[-3pt] -1 \end{array}
In this way, the long division process continues, until the remainder is not less than the denominator value.
Step 3:
After division, rewrite the original rational function as the sum of the polynomial quotient and the remainder divided by the original denominator.
$$ \frac{x^3 + 2x^2 + x + 1}{x^2 + 1} \;=\; x + 2 + \frac{-1}{x^2 + 1} $$
Step 4:
Now you can use the partial fraction method to simplify more to make the integration process smooth.
