极坐标转直角坐标转换工具

转换方法说明

将极坐标 (r, θ) 转换为直角坐标 (X, Y) 的过程如下:

  • 转换公式

    • x = r * cos(θ/180 * π)
    • y = r * sin(θ/180 * π)
  • 输入输出说明

    • 输入:极坐标 r 和 θ
    • 输出:直角坐标 (X, Y)
  • 示例转换

    输入示例

    • r = 10
    • θ = 45°

    转换结果

    • X = 10 * cos(45°/180 * π) ≈ 7.071068
    • Y = 10 * sin(45°/180 * π) ≈ 7.071068

    代码实现

    #include 
    #include
    #define PI 3.1415926int main() { double r, theta; printf("极坐标r值和theta值: "); scanf_s("%lf %lf", &r, &theta); // 计算直角坐标 x = r * cos(theta / 180 * PI); y = r * sin(theta / 180 * PI); printf("直角坐标: (%f, %f)\n", x, y);}

    结果展示

    极坐标r值和theta值: 10 45直角坐标: (7.071068, 7.071068)
