One-Sided Limits

One-Sided Limits

Also called "right-handed" and "left-handed" limits, these are the ones where they put a little plus or minus sign to the right of the number. For example, 2+ would mean "limit as x approaches 2 from the right." These have a lot of graphing to them, so you'll definitely want to watch the previous video about graphical limits first.

One-Sided Limits Analytically (Algebraically)

In the first video we covered one-side limits based on graphs. In this video we cover left-hand and right-hand limits in equation form, including how to tell if they're approaching positive or negative infinity. Plugging in, as usual, is our best strategy!
