Why Learn Partial Fractions?
- Scoring Topic: Frequently asked in board exams.
- Foundation for Higher Classes: Essential for algebra and calculus in Class 11 and 12.
- Practical Applications: Used in engineering, physics, and economics for simplifying complex equations.
Understanding Partial Fractions
A partial fraction is a way of breaking down a complex rational function into simpler fractions. The process, called partial fraction decomposition, helps in integration, differential equations, and algebraic simplifications.
Types of Partial Fractions
- Proper Fractions: The degree of the numerator is less than the degree of the denominator.
- Improper Fractions: The degree of the numerator is equal to or greater than the denominator.
For improper fractions, divide first to get a proper fraction before applying decomposition.
Methods of Partial Fraction Decomposition
- Non-Repeated Linear Factors:
\frac{P(x)}{(x - a)(x - b)} = \frac{A}{x - a} + \frac{B}{x - b}
- Repeated Linear Factors:
\frac{P(x)}{(x - a)^2} = \frac{A}{x - a} + \frac{B}{(x - a)^2}
- Non-Repeated Quadratic Factors:
\frac{P(x)}{(x^2 + px + q)} = \frac{Ax + B}{x^2 + px + q}
- Repeated Quadratic Factors:
\frac{P(x)}{(x^2 + px + q)^2} = \frac{Ax + B}{x^2 + px + q} + \frac{Cx + D}{(x^2 + px + q)^2}
Step-by-Step Partial Fraction Decomposition
- Factorize the denominator, if possible.
- Write the partial fraction form using the appropriate method.
- Multiply through by the denominator to eliminate fractions.
- Compare coefficients or substitute values to solve for unknown constants.
- Rewrite the expression with the calculated values.
