直角坐标系(Rectangular Coordinate System),又稱笛卡爾坐标系(Cartesian Coordinate System),是一種用垂直相交的坐标軸描述平面或空間中點位置的數學工具。以下是詳細解釋:
基本定義
由法國數學家笛卡爾提出,通過一組互相垂直的坐标軸(如x軸和y軸)構建網格系統。平面中每個點的位置由唯一的有序數對$(x, y)$表示,空間内則由三元組$(x, y, z)$表示。

與其他坐标系的對比
相較于極坐标系(用半徑和角度定位)、柱坐标系或球坐标系,直角坐标系更直觀地通過垂直投影确定位置,適合處理線性關系和正交方向的問題。
例如:點$(3, 4)$在平面坐标系中表示從原點向右移動3單位,再向上移動4單位的位置;三維點$(2, -1, 5)$則需額外沿z軸正方向移動5單位。
