I am taking calc I online at a local college. There are no lectures to watch. I try to match up your lectures with what I am doing but the only way to search is through the titles of your sections. Could you please be more specific in what the "examples" are? It would help out quite a bit when I need to find a way to answer a problem in my course.

This lesson teaches us as if we already know what limits are, but this is the only video I can see that discusses them. Is there another video I am missing?

I don't know if saying approaches zero from smaller and bigger values is appropriate. You can have small positive and negative values...

  • Remember that we are looking at what happens as approaches (not what happens at ).
  • For limits as , we are looking at what happens as x increases or decreases without bound.
  • Numerical work with limits does not constitute a proof, but it can give us confidence in results we have obtained by other means.
  • If you are working numerically with trigonometric functions, work in radian mode.
