Partial Fraction Decomposition Concepts

The video tutorial introduces the concept of partial fractions, explaining how a single fraction can be decomposed into two or more simpler fractions. The process involves combining fractions, comparing coefficients, and solving equations to find the values of unknowns. The tutorial also covers the differentiation of partial fractions using calculus, highlighting the simplification it offers. The video concludes with a discussion on the applications of partial fractions in mathematical problems.
