13.13.5 The rectangular coordinates of a point: rectangular_coordinates
The rectangular_coordinates command finds the rectangular
coordinates of a point given its polar coordinates.
-
rectangular_coordinates takes two arguments:
r, θ, two real numbers.
- rectangular_coordinates(r,θ)
returns a list of the rectangular coordinates of the point with
polar coordinates r and θ.
Example.
Input:
rectangular_coordinates(2, pi/4)
or:
rectangular_coordinates(polar_point(2, pi/4))
Output:
