This Computer Algebra System (CAS) activity shows how the method of dynamization by parameterization works with almost all classical math problems, which produces problems for CAS calculators quickly.

Before the Activity

Install TI Connect™ using the TI connectivity cable

See the attached PDF file for detailed instructions for this activity

During the Activity

Distribute the pages to the class.

Follow the Activity procedures:

Solve a classical fractional equation problem

Find the area of a triangle with given vertices using Heron's formula

Take a geometric or an algebraic approach to solve a vector equation problem

Understand the concept of a transversal, and use it to solve problems

Given two points on a line, find a point on the line which satisfies the Apollonius sphere condition

Determine the center and radius of a circle given 3 peripheral points

Examine the dynamization of the classical problems
