c语言输入一个度，计算三角函数sin和cos的值的代码

#include <stdio.h>
#include <math.h>

int main() {
double degree, radian, sin_value, cos_value;
printf("请输入一个角度：");
scanf("%lf", &degree);
radian = degree * M_PI / 180.0;
sin_value = sin(radian);
cos_value = cos(radian);
printf("sin(%lf) = %lf\n", degree, sin_value);
printf("cos(%lf) = %lf\n", degree, cos_value);
return 0;
}
