26.5.5  Points in polar coordinates

The point command can be used for specifying a point in polar coordinates by using the polar representation of complex numbers, e.g.

which is the point with polar coordinates r=2, θ=π/4.

The polar_point or point_polar command is an easier way to specify a point in polar coordinates.

• polar_point takes two arguments:
  • r, a number.
  • θ, a number.
• polar_plot(r,θ) returns and draws the point with polar coordinates r,θ.

Example

which is the same point as before.
