Unit 2 - Limits
2.1 The Tangent Problem
This section introduces tangent and secant lines. On the video I did not actually draw the lines PQ because they make the sketch too complicated. You need to imagine that each secant line PQ that I talk about is a line on the sketch and, as Q gets closer to P the slope of the secant approaches the slope of the tangent line at P.
Please watch the video and then move onto the next section.

2.2 The Limit of a Function: Continuous
You will need to print the Properties of Limits information sheet before starting 2.2. Click on the red letters to the left and print the page.
This section introduces the idea of a limit. Functions can be continuous when there is no break in the function or discontinuous when there is a break in the function. This section explains continuous functions.

2.3 The Limit of a Function: Discontinuous
A discontinuous function may or may not have a limit, depending upon if the point of discontinuity is a "hole" or an "asymptote". This section focuses on discontinuous functions that have a limit - those with a "hole".

2.5 One-Sided Limits: Graphs
This section takes another look at discontinuous functions that do not have limits. The graphs will show that they can have limits when approached from only one side.
