Equations of Lines in Polar Coordinates
In the study of polar equations we must learn how to write the equation of a polar coordinates line. Students are sometimes asked to use the distance formula for polar coordinates, or to find the equation of the polar coordinates line in rectangular form, so students should know how to convert points on the polar coordinates line from polar to rectangular, and from rectangular to polar coordinates and how to find the polar equation of a line through the origin (or pole).
