4.1 Graphing in Two Dimensions • 101Polar CoordinatesCartesian (ordinary) coordinates is the Maple default and is one amongmany ways of specifying a point in the plane. Polar coordinates, (r, θ),can also be used.In polar coordinates, r is the distance from the origin to the point,while θ is the angle, measured in the counterclockwise direction, betweenthe x-axis and the line through the origin and the point.Maple can plot a function in polar coordinates by using the polarplotcommand. To access the short form of this command, you must first employthe with(plots) command.> with(plots):
