Understanding Limits and Function Behavior

The video introduces the basics of calculus, focusing on the concept of limits. It begins by plotting a function Y for various X values, highlighting an undefined value at X=1 due to division by zero. The video explains how to approach X=1 from both sides to understand limits, demonstrating that as X approaches 1, Y approaches 2. The concept of limits is crucial in calculus, especially when dealing with undetermined values. The video concludes with a call to action for viewers to like and subscribe for more educational content.
