Points in polar coordinates: polar_point point_polar

### 13.6.5 Points in polar coordinates: polar_point point_polar

You can use the point command to specify a point in polar coordinates by using the polar representation of complex numbers.

#### Example.

Input:

point(2*exp(i*pi/4))

Output:

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

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

- 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.

Input:

polar_point(2,pi/4)

Output:

which is the same point as before.
