Definition of polar coordinates in English:

polar coordinates

plural noun

Geometry

1A pair of coordinates locating the position of a point in a plane, the first being the length of the straight line (r) connecting the point to the origin, and the second the angle (θ) made by this line with a fixed line.
〔几何〕（平面）极坐标
Example sentencesExamples
- If we insist on unbiasedness, we must choose c so that E = [mu] uniformly in [mu]. To think about that, we first express the problem in polar coordinates.
- The same formula can be expressed in polar coordinates, where the locations of points are expressed in terms of angle, q, and distance, r, from the origin rather than x and y coordinates.
- On page 149, Pesic mentions de Moivre's discovery of the formula (cos [theta] + i sin [theta]) n = cos n [theta] + i sin n [theta] and implies that to prove it one needs to think about complex numbers in polar coordinates.
- It was based on polar coordinates whereas earlier instruments were based on cartesian coordinates.
- Cartesian and polar coordinates are great tools in the analytic geometry of the plane.
1. 1.1 The coordinates in a three-dimensional extension of polar coordinates.
  （立体）极坐标
  Example sentencesExamples
  Since the profile is a curved shape, it's much easier mathematically to use what are known as as polar coordinates.
