TI-89 Activities for PreCalculus and AP Calculus

#### Activity Overview

In this Computer Algebra System (CAS) activity, students use the statistical, graphical, and symbolic capabilities of the calculator to make it a powerful tool for investigating and developing mathematical concepts.

#### Before the Activity

• Install TI Connect™ using the TI connectivity cable
• See the attached PDF file for detailed instructions for this activity
• Print pages 1 - 21 from the attached PDF file for the class
• #### During the Activity

Distribute the pages to the class.

Follow the Activity procedures:

• Explore the numerous commands, features, and calculation capabilities of the calculator
• Use the calculator to solve a system of equations by elimination method, substitution method, and matrix method
• Find the inverse of a function

• With the help of the statistical and graphical capabilities of the calculator, solve a given problem, and derive an equation that models the problem situation
• Use the symbolic algebra capabilities to derive an equation that represents problem situations without using graphs
• Enter the data for the problem situation and set up a scatter plot
• Perform a quadratic regression
• Explore other algebra-graph connection problems

• Explore the summation commands
• Use patterns to develop formulas for exponents, logarithms, rationalizing denominators, and factoring
• Understand how parametric and trigonometric problems can be solved using the calculator
• Develop the power rule from y = xn
• Use the calculator to solve various problems that appeared on the AP Calculus exam

• Determine where the derivative of a function is equal to zero
• Find the derivative of a function and use the calculator to verify the result
• Study the Chain Rule
• #### After the Activity

Students' answer questions on the Activity sheet.

Review student results:

• As a class, discuss questions that appeared to be more challenging
• Re-teach concepts as necessary
