Graphing Polar Equations on the TI-84

This tutorial guides users through graphing polar equations on a TI-84 calculator. It covers setting the calculator to degree and polar modes, configuring the window and table settings, entering polar equations, and analyzing graphs using trace and table functions. The video provides step-by-step instructions to ensure accurate graphing and analysis of polar coordinates.
