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

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?

Limit Investigations

  • 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.
