C++ :

#include <iostream>
#include <cmath>

using namespace std; // 使用标准命名空间

int main() {
    double angle_degrees = 60.0;
    double angle_radians = angle_degrees * M_PI / 180.0;

    double sin_value = sin(angle_radians); // 计算正弦值
    double cos_value = cos(angle_radians); // 计算余弦值

    cout << "Angle in degrees: " << angle_degrees << endl;
    cout << "Angle in radians: " << angle_radians << endl;
    cout << "Sine value: " << sin_value << endl;
    cout << "Cosine value: " << cos_value << endl;

    return 0;
}
