Partial fractions

Partial fractions is a mathematical technique used to decompose a rational function into a sum of simpler fractions, called partial fractions. This method is particularly useful in algebra, calculus, and differential equations, as it simplifies the process of integrating rational functions. A rational function is typically expressed as the ratio of two polynomials, say \( \frac{P(x)}{Q(x)} \), where \( P(x) \) and \( Q(x) \) are polynomials.
