Activity Overview

This activity is an application of integration. Students first use the calculator to determine specific numeric results to enable them to understand the dynamics of the problem.

Before the Activity

Students then use the symbolic capacity of their calculator and derivatives to find the maximum volume. This activity emphasizes using the integral of a rate of change to give the accumulated change. The definite integral of the rate of change of a quantity is interpreted as the change of the quantity.
See the attached Activity PDF file(s) for detailed instructions for this activity.

During the Activity

Follow the procedures outlined in the activity.
Students will:

  • Be able to use the calculator to determine specific numeric results in the context of the problem.
