In this lesson you will learn
By the end of this section students will be able to:
Several problems involving the calculation of an instantaneous rate of change have been solved in the previous section. No doubt some, if not all, of them took a great deal of time to solve. The purpose of this section then, is to offer other ways of finding the instantaneous rate of change; namely, the derivative. As the title of this section suggests, the derivative is the general formula for the slope of the tangent at any point on a graph.
The latter part of the section will involve the investigation of the graph of the slope function of the original function. This graph can provide key information about the shape of the original graph. Thus, by the end of this section, you should have a greater understanding of how slope is connected to the shape of a graph.
It should take 6 to 7 hours to complete this section.
To be successful in this lesson, it would be helpful to know the following:
