Video utilizing the Squeeze Theorem to prove that the limit as x approaches 0 of (sin x)/x is equal to 1. Incorporates trigonometry and the unit circle. Illustrates the result graphically on a virtual graphing calculator. This video is...

The limit is explored in this video lesson. In the video Josh explores the intuitive notion of limit from playground slides to food processors.

Students learn about the epsilon-delta definition of limit. Josh plays the epsilon-delta game and visits the For All There Exists Cafe as he explains the formal definition of limit in these video lessons.

This lesson shows how a limit may be found for an element of the domain of a function by substituting that value into the function. It is 6 of 7 in the series titled "Finding a Limit Through Substitution."

Given a sequence, this lesson demonstrates how to relate it to a function to find the limit. It is 1 of 7 in the series titled "Using a Function to Find a Limit."

This lesson explains how the left and right limits for a value of the domain of a function relate to the concept of convergence.

This lesson introduces the concept of secant lines. It is 3 of 5 in the series titled "Secant Lines."

Video addresses limits of rational functions that can be simplified by factoring. Also provides examples of how to find the limit of a function as x approaches infinity.

Instructional video explaining the Squeeze Theorem. The theorem is first described using a real-life situation, then the theorem is illustrated graphically using three arbitrary functions. Does not include a proof of the theorem. This...

This video is an intuition (but not a proof) of the Squeeze Theorem.
