This calculus video tutorial provides a basic introduction into the definition of the derivative formula in the form of a difference quotient with limits. It explains how to find the derivative of a function using the limit process. This video contains plenty of examples and practice problems.

Here is a list of topics:

1. Derivative of x^2

2. Derivative of rational functions – 1/x

3. Derivative of radical functions – square root of x

4. Derivative of linear functions
