This section explores the concept of limits in calculus, emphasizing their importance and utility. It provides examples of how to estimate limits using tables of values and graphical representations. Theorems involving limits, including those related to trigonometric, exponential, and logarithmic functions, are presented with practical examples to solidify understanding. Students will learn to evaluate limits analytically and discover the significance of the Squeeze Theorem. Engaging with these concepts will enhance comprehension of calculus principles and their applications.
