With this calculator you can convert cartesian coordinates of a point into polar coordinates and vice versa. The cartesian coordinates of a point are the value of the abscissa x an the ordinate y. The polar coordinates are the radius r for the distance between the point and the pole (the origin of the cartesian coordinate system) and the angle Θ (or azimut) for the angle (anticlockwise) between the axis with the angle 0° (corresponding to the abscissa in the cartesian coordinate system) and the point.

Usage:
Type the cartesian coordinates or the polar coordinates of a point into the
corresponding fields. After a click with the mouse on any free space of the window
or the "calculate"button the calculation is performed.
The fields with input data get a lightgreen background, fields with calculated
values are coloured pink. The calculation is performed with the pair of coordinates
changed last.
Move the mouse over a unit or click on it to read its full name.
Click on the "reset"button to reset the calculation.
Example: What are the polar coordinates of the point with the cartesian coordinates x=3 und y=5 ? After a click with the mouse on any free space of the window or the "calculate"button you can read the result. The radius (the distance between the origin and the point) is 5.831. The angle between the connection origin to point and the abscissaaxis is 59.036°. This value corresponds to 1.0304 radians or 0.32798*π.
