Lesson Summary:

This lesson covers rates of change and related rates using examples in different contexts such as temperature, area, velocity, population growth, and electrical circuits. The derivative is introduced as the instantaneous rate of change, and related rates problems are solved using implicit differentiation and the chain rule. The lesson also includes a demonstration of how to find the rate at which a spotlight moves past a point on the shoreline, and the rate at which a tank with a cone shape fills up with water.

Lesson Description:

The derivative as rate of change. Related rates problems.

    This video represents the derivative as a rate of change. Some real-life situations are explained with their units, the dependent / independent variable, and the rate of change in the situation. A ball dropping situation is used as an example of velocity being the derivative of the height function. An example of a pond being stocked with fish is also used to explain rate of change. Several more examples, including a couple of classic Calculus problems, are explained well in this video.
