This calculus video tutorial shows you how to calculate the average and instantaneous rates of change of a function. This video contains plenty of examples and practice problems.
Here is a list of topics:
1. How to find the average rate of change of a function over an interval
2. Instantaneous rate of change at a point
3. Average rate of change - slope of the secant line between two points on a graph
4. Instantaneous Rate of Change - Slope of tangent line at a single point on the curve
5. Estimating the instantaneous rate of change using the average rate of change formula
6. Calculating the derivative as a function using limits as the change of x approaches zero
7. Determining the slope of the tangent line using limits
8. Average rate of change between two points
9. Finding the derivative using the limit process
