如何在c++数学中获取基于方向的坐标

#include <iostream>
#include <cmath>

struct Point {
    double x;
    double y;
};

// 计算两点之间的距离
double calculateDistance(const Point& p1, const Point& p2) {
    double dx = p2.x - p1.x;
    double dy = p2.y - p1.y;
    return std::sqrt(dx * dx + dy * dy);
}

// 计算给定点在指定方向上的新坐标
Point calculateCoordinate(const Point& origin, double distance, double direction) {
    double angle = direction * M_PI / 180.0;  // 将角度转换为弧度
    double x = origin.x + distance * std::cos(angle);
    double y = origin.y + distance * std::sin(angle);
    return {x, y};
}

int main() {
    Point origin = {0.0, 0.0};
    double distance = 5.0; // 距离原点的距离
    double direction = 45.0; // 方向，以角度表示

    Point newCoordinate = calculateCoordinate(origin, distance, direction);
    std::cout << "New Coordinate: (" << newCoordinate.x << ", " << newCoordinate.y << ")" << std::endl;

    return 0;
}
