直角坐标系(Rectangular Coordinate System),又称笛卡尔坐标系(Cartesian Coordinate System),是一种用垂直相交的坐标轴描述平面或空间中点位置的数学工具。以下是详细解释:
基本定义
由法国数学家笛卡尔提出,通过一组互相垂直的坐标轴(如x轴和y轴)构建网格系统。平面中每个点的位置由唯一的有序数对$(x, y)$表示,空间内则由三元组$(x, y, z)$表示。
核心组成
应用领域
与其他坐标系的对比
相较于极坐标系(用半径和角度定位)、柱坐标系或球坐标系,直角坐标系更直观地通过垂直投影确定位置,适合处理线性关系和正交方向的问题。
例如:点$(3, 4)$在平面坐标系中表示从原点向右移动3单位,再向上移动4单位的位置;三维点$(2, -1, 5)$则需额外沿z轴正方向移动5单位。
