polar coordinates

名詞

複数形 複数形のみ

(mathematics) The coordinates of a point in a plane, measured as its Cartesian distance from the origin and the angle measured anticlockwise/counterclockwise from the x-axis to a line joining the point to the origin.

日本語の意味

極座標 - 平面上の点の位置を、原点からの距離とx軸から点を結ぶ線との間の角度（反時計回りで測定）で表す座標系

Before integrating, convert the function into polar coordinates so the radial symmetry becomes apparent.

積分を行う前に、関数を原点からの距離と反時計回りに測った角で表す極座標に変換すると、放射状の対称性が明らかになります。

意味（1）

(mathematics) The coordinates of a point in a plane, measured as its Cartesian distance from the origin and the angle measured anticlockwise/counterclockwise from the x-axis to a line joining the point to the origin.

意味（2）

(mathematics) The coordinates of a point in three-dimensional space, measured as its Cartesian distance from the origin, the angle measured from the z-axis to a line joining the point to the origin, and the angle measured anticlockwise from the x-axis to this line.
