The coordinate input method mainly includes

Absolute rectangular coordinates, absolute polar coordinates, relative polar coordinates.

According to the query and display of APP, the coordinate input methods mainly include absolute rectangular coordinates, absolute polar coordinates and relative polar coordinates. 1, absolute Cartesian coordinates: based on a point (usually the origin), determine the position of another point by inputting values in the X and Y directions.

2. Absolute polar coordinates: Based on one pole, the position of another point is determined by inputting the polar diameter and polar angle. The polar diameter represents the distance from the point to the pole, and the polar angle represents the included angle from the point to the positive direction of the polar axis.

3. Relative polar coordinates: In the relative polar coordinates system, the position of an object is described by its distance and direction relative to the last known point.
