Precalculus: Infinite Geometric Series
by Texas Instruments

Published on August 15, 2011

Overview

Students explore infinite geometric series. They will consider the effect of the value for the common ratio and determine whether an infinite geometric series converges or diverges.

Key Steps

  • Image

    In this activity, students will explore infinite geometric series graphically and numerically by changing the common ratio determining for which values the series converges or diverges. Then will then create a scatter plot of the partial sums.

  • Image

    Students will apply knowledge of the formulas for the sum of finite and infinite geometric series through a medication and drug dosage problem.
