102 • Chapter 4: GraphicsFigure 4.1 The Polar Coordinate Systemyrθ0xUse the following syntax to plot graphs in polar coordinates.polarplot( r-expr, angle=range )In polar coordinates, you can specify the circle explicitly, namely as r = 1.> polarplot( 1, theta=0..2*Pi, scaling=constrained );10.5–1 –0.5 0.5 1–0.5–1Use the scaling=constrained option to make the circle appearround. Here is the graph of r = sin(3θ).> polarplot( sin(3*theta), theta=0..2*Pi );
