Partial Fraction Decomposition

What is Partial Fraction Decomposition?

Partial fraction decomposition is a method used to break down a complex algebraic fraction into simpler parts. This technique is particularly useful in calculus, especially when integrating rational functions or solving differential equations.

How to Use the Partial Fraction Decomposition Calculator

  1. Enter your complex fraction in the input field.
  2. Click the “Calculate” button.
  3. View the step-by-step solution and simplified result.

Our calculator handles various types of fractions, including proper and improper fractions, as well as those with linear and quadratic factors in the denominator.

The Process of Partial Fraction Decomposition

Understanding the process can help you appreciate what the calculator does:

  1. Factor the denominator of the fraction.
  2. Set up partial fractions based on the factors.
  3. Find a common denominator and equate the numerators.
  4. Solve the resulting system of equations.
  5. Combine the results to get the final decomposed form.

Examples of Partial Fraction Decomposition

Let’s look at a few examples to illustrate how this works:

Example 1: Simple Linear Factors

For the fraction (2x + 1) / (x^2 - 1), the decomposition would be:

A / (x - 1) + B / (x + 1)

Example 2: Repeated Linear Factor

For (x + 2) / (x^2 + 2x + 1), we get:

A / (x + 1) + B / (x + 1)^2

Example 3: Quadratic Factor

For (2x + 1) / (x^2 + 1), the result is:

(Ax + B) / (x^2 + 1)

Applications of Partial Fraction Decomposition

This technique is used in various fields:

  • Integration in calculus
  • Solving differential equations
  • Signal processing in engineering
  • Control systems analysis
  • Laplace transform calculations

Tips for Using the Calculator

  • Always simplify your fraction before inputting it into the calculator.
  • Check if your fraction is proper (numerator degree less than denominator degree). If not, perform polynomial long division first.
  • Verify the result by combining the decomposed fractions back together.

Common Mistakes to Avoid

  1. Forgetting to factor the denominator completely.
  2. Overlooking repeated factors in the denominator.
  3. Incorrectly setting up the partial fractions for quadratic factors.
