Understanding Limits of Hyperbolic Functions

The video tutorial explains how to evaluate the limits of hyperbolic functions, including hyperbolic sine, tangent, secant, and cotangent. It emphasizes the importance of graphing these functions to understand their behavior as x approaches infinity, negative infinity, and zero. The tutorial covers the concept of horizontal and vertical asymptotes and demonstrates how to determine the limits by analyzing the graphs.
