#include<stdio.h>
  #include<math.h>
  int main(void)
  {
     double result, x = 0.5;
     result = sin(x);
     printf("The sin() of %lf is %lf\n", x, result);
     return 0;
  }

• For More Accurate Result We should use Mathematical Constant M_PI
• Angles are specified in radians.

Angle	Symbolic Version
180	M_PI
90	M_PI / 2
60	M_PI / 3
45	M_PI / 4
30	M_PI / 6
