# Power Series and Limits

Power series and limits are fundamental concepts in calculus and mathematical analysis, serving as crucial tools in understanding the behavior of functions. A power series represents a function as an infinite sum of terms, each involving powers of a variable. By exploring the convergence or divergence of these series through limits, mathematicians can ascertain their applicability in various contexts, from approximating functions to solving differential equations. Understanding the interplay between power series and limits provides insights into the intricate structures of mathematical functions and enables precise calculations in areas ranging from physics to engineering and beyond.
