|coordinate conversion/change of coordinates;[數]坐标變換
坐标變換（Coordinate Transformation）是指将一個坐标系中的點或數據轉換到另一個坐标系中的數學過程，廣泛應用于數學、物理學、工程學和計算機科學等領域。以下是詳細解釋：
begin{pmatrix} costheta & -sintheta sintheta & costheta end{pmatrix} begin{pmatrix} xy end{pmatrix} $$
若要将極坐标系 $(r, theta)$ 轉換為笛卡爾坐标系 $(x, y)$： $$ x = r costheta, quad y = r sintheta $$ 反向變換則為： $$ r = sqrt{x + y}, quad theta = arctanleft(frac{y}{x}right) $$
坐标變換的核心目标是簡化問題分析或實現不同系統間的數據兼容性。掌握其原理對解決多學科複雜問題至關重要。
用法： Coordinate（坐标）是一個表示位置的系統，通常用于在二維或三維空間中描述點或物體的位置。坐标通常由一個或多個數值組成。在二維平面坐标系中，一個點的坐标通常由兩個值（x，y）表示，而在三維空間中，一個點的坐标通常由三個值（x，y，z）表示。
例句：
近義詞： location, position, point
反義詞： discoordinate, disordered
用法： Transformation（變換）是指在數學、物理學和工程學中，将一個對象或系統從一種形式或狀态轉換為另一種形式或狀态的過程。在數學中，變換通常指線性變換、仿射變換和歐幾裡得變換等。在計算機科學中，變換通常指圖像變換和幾何變換等。
例句：
近義詞： conversion, metamorphosis, change
反義詞： stability, constancy
