Evaluate the limit using sine and cosine special limits

The video tutorial discusses the concept of limits, focusing on why direct substitution cannot be applied in certain cases. It explains how to manipulate expressions to evaluate limits, specifically using sine and cosine functions. The tutorial demonstrates breaking down limits into parts for easier calculation and emphasizes practicing limit properties to reinforce understanding.

What is the significance of breaking apart limits according to the teacher?

Why does the teacher spend extra time on the limit properties?
