How to use special trig limits to evaluate the limit

The video tutorial explains how to group terms and use a trick property to factor out constants in a mathematical expression. It demonstrates evaluating the limit of sine of X over X as X approaches zero, which equals 1. The tutorial also includes a graphical interpretation of the result, showing it crosses at 1.66, equivalent to 5/3. The session concludes with a brief summary of the findings.
