Example 7.3 - Plotting curves in polar coordinates

In this example we will plot Freeths Nephroid given by equation r=a(1+2sin(phi/2))

export(plot,polar);
   Nephroid := polar(
   [1+2*sin(phi/2), phi], phi=0..4*PI,
   Grid = [100],
   Color = [0,0,1],
   LineWidth = 10
):
 

plot(
   Nephroid,
   Scaling = Constrained,
   BackGround = [0.8, 0.8, 1],
   ForeGround = [0, 0, 0],
   Title = "Nephroid",
   FontSize = 11,
   FontStyle = "bold"
)
