Introduction to Power Series

Power series are fundamental mathematical constructs used extensively in calculus, analysis, and various branches of physics and engineering. Represented as infinite series of terms involving powers of a variable, they offer a versatile tool for approximating and understanding functions. Each term's coefficients and powers contribute to the series' behavior, allowing for precise manipulation and analysis. Through the study of convergence properties, differentiation, and integration, power series facilitate the exploration of complex functions and their behavior near specific points. This introductory overview sets the stage for delving into the rich mathematical landscape governed by power series.
