## Backwards Design

Course Objectives

• Primary Objectives- By the next class period students will be able to:
• Use Taylor series to calculate numerical values of a function
• Sub Objectives- The objectives will require that students be able to:
• Calculate the coefficients of the Taylor series
• Find an error estimate for the Taylor series
• Difficulties- Students may have difficulty:
• With finding the error bound
• To know when the Taylor series diverges
• Real-World Contexts- There are many ways that students can use this material in the real-world, such as:

## Legacy Cycle

OBJECTIVE

By the next class period, students will be able to:

• Use Taylor series for numerical computation.

The objectives will require that students be able to:

• Calculate Taylor series

THE CHALLENGE

You are working for a Calculator Manufacturer. The hardware was recently improved and there is a new scrolling screen available. The CEO of the company offers a \$2000 bonus to the mathematician who can design a method to calculate sin x with 100 decimals.

The calculator is already equipped with software to use the scrolling screen feature for elementary operations.

GENERATE IDEAS

Explain the challenge and ask for opinions.

MULTIPLE PERSPECTIVES

The students work in small groups for 10 min and come up with ideas.

RESEARCH & REVISE

• The professor introduces the Taylor series.
• The students calculate the Taylor series of sin X.
• The professor asks the students how we can insure that the solutions to 100 decimals are exact.
• The students revise their ideas. The error needs to be estimated.
• The professor teaches the error estimate.
