Evaluate the limit of sinx over x

The video tutorial discusses the limitations of graphing calculators in identifying holes and asymptotes. It emphasizes the importance of understanding these concepts fundamentally. The tutorial explains how to use scientific calculators to calculate limits by choosing values close to zero and testing both left and right limits. The example provided shows that as values approach zero, the result approaches one, confirming the limit.

What steps should you take if you do not have a graphing calculator to analyze a function?

How can you confirm that the limit as X approaches zero is one?
