Section 1.4 - One Sided Limits
In the last lecture, we saw some situations that were a little awkward. $\lim\limits_{x\to 0} \sqrt{x}$, for example, doesn't exist because the function is undefined to the left of 0. This is a little awkward since the function is perfectly "well behaved" on the right side. We can resolve this with what are called "one sided limits".

Lectures
Sometimes it's convenient just to look at what a function is doing on one side of a number, rather than both sides. This will give us a way to talk about functions that aren't defined everywhere and to find the limits of more functions. (lecture slides)
