Implicit Differentiation

Activity Overview

Students differentiate an equation in two variables with respect to one. They calculate points where the tangent line is horizontal, vertical, or oblique and use the graphing capacity of the TI-89 to display the graph of the implicit function.

Before the Activity

Students should have access to TI-89/TI-89 Titanium and TI-92 Plus/Voyage.

During the Activity

The document attached is the activity guide. Provide each student with a printed copy of this document.

After the Activity

Review student results and, as a class, discuss questions that appeared to be more challenging. Re-teach concepts as necessary.
