In this lesson you will download and execute a script that develops another rule for finding antiderivatives. Once the script is on your TI-89 you can execute it to discover the indefinite integral rule by evaluating three types of indefinite integrals that each have the form
. You will then be asked to find a general rule for indefinite integrals that have the same form.

Finding
The script intconst walks you through the discovery process of finding the general rule for
by evaluating examples of the integrals shown below and predicting a general rule for each type:
You may want to record the results of the calculations for use in making a prediction. When prompted to make a prediction, write your response before proceeding to the next command.
