Activity Overview
This activity introduces students to an interesting property of fourth degree polynomials and a method of proving that property using the TI-89 scripts. They then use the CAS of their TI-89 to generalize upon specific results.
Before the Activity
Students should have access to the TI-89/TI-89 Titanium and TI-92 Plus/Voyage 2000.
During the Activity
This activity introduces students to an interesting property of fourth degree polynomials and a method of proving that property using the TI-89 scripts. They then use the CAS of their TI-89 to generalize upon specific results. The document attached is the activity guide.
After the Activity
Review student answers:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
