Think of a limit as what you think is going to happen, based on what you observe.  Cliffhangers for TV series often work this way; they set up a scene, and make it appear as though something is about to happen, but we don't necessarily know if it is going to go down that way.  A limit is kind of the same thing.  You will observe, graphs, look at the trend or pattern, and then guess what is going to happen at a specific point on the graph without actually know what happens there.  This is a limit.  Find out more about limits and some of the terminology we use with them.

Things you should know after today:

• definition of a limit
• the difference between one-sided and two sided limits
• properties of limits (combining limits
• how to find limits by substituion
• finding limits that can't be evaluated by direct substitution
• finding limits graphically
