In this initial video, we will review the Warm-Up Problems and introduces the idea of a limit as approaching some value without having to get there. Duration: 8:11

Here is the informal definition of a limit, because, let's face it, the formal definition looks all Greek to me. Turns out, you've known about limits for quite some time; it's just that nobody told you. Blame your geometry teacher, whoever that guy was. Duration: 13:39

For those of you curious for an explanation of the formal epsilon-delta definition of a limit, Sal Khan has a game for you. Duration: 6:58

In Examples 1 and 2, we estimate the value of a couple of limits graphically and numerically. Toward the end there, you'll see the best way to construct your table to easily visualize where a limit is headed. Duration: 10:15

Let's take another look at Example 2, this time algebraically. Essentially, this is how you would have found the y-value of the hole for a point of discontinuity (missing googly-eye) back in Algebra 2. Duration: 4:33

Do you have a TI-84 Plus calculator? This video will demonstrate how you can use it to build a custom table of values to estimate a limit numerically. Just so you know, we're using Example 2. Again. Duration: 3:28

On Examples 3 and 4, we further perfect our limit estimating techniques. Duration: 7:38

This video will reveal some advanced graphing techniques for you TI-84 aficionados. Specifically, I'll show you how to graph piecewise functions using conditions found in the Test Menu. Duration: 5:13
