Understanding Limits in Calculus

The video tutorial introduces the concept of limits in calculus, explaining how to find limits as a variable approaches a specific value. It covers different types of functions, including polynomial, rational, and trigonometric functions, and demonstrates the use of direct substitution to evaluate limits. The tutorial provides examples and calculations to illustrate the process of finding limits, emphasizing the importance of understanding when a function is undefined and how to approach such cases.
