Great teaching! Thanks!

Limit Definition of the Derivative

  • Be careful in your work with - it is a function composition!
  • Also take care in carrying out the subtraction ; realize we are subtracting off the entire quantity given by .
  • The work here for and is famous and involves a couple famous limits.
  • If you know how to compute derivatives directly, you can check your result by this means.
