Скачать или смотреть An Introduction to Infinite Series

In this video, we introduce the concept of infinite series in calculus. You’ll learn what a series is, how we define partial sums, and why they matter when studying convergence. To make things concrete, we work through a classic example.
​
We’ll explore how its partial sums behave, and why this geometric series converges to 2.

This is the foundation for understanding more advanced convergence tests and series techniques later in calculus. Perfect for students just getting started with infinite series!
