编写C语言程序求35度角的正弦余弦正切余切

#include

#define PI 3.1415

void main()
{
double var, sinRes, cosRes, tagRes, ctgRes;

var = 35*PI/180;
sinRes = sin(var);
cosRes = cos(var);
tagRes = sin(var)/cos(var);
ctgRes = cos(var)/sin(var);

printf("sin: %.2lf\n", sinRes);
printf("cos: %.2lf\n", cosRes);
printf("tag: %.2lf\n", tagRes);
printf("ctg: %.2lf\n", ctgRes);
}
//测试结果：
