Polar Form of a Line - Graphing Lines on the Polar Grid

This lesson explains how to convert linear equations between rectangular and polar forms using x = r cos θ, y = r sin θ, r² = x² + y², and tan θ = y/x. It also demonstrates strategies for graphing lines, including horizontal and vertical lines, on the polar grid.
