Math Functions (Using COSINE Function)

Write a program to show the use of Math Functions.

Hints: We often use standard mathematical functions such as cos,sin,exp,etc. We shall see now the use of a mathematical function in a program. The standard mathematical functions are defined and kept as a part of C math library.

#include<math.h>
#define PI       3.1416
#define MAX       180
main()
{
 int angle;
 float x,y;
 angle = 0;
 printf("        Angle        Cos(angle)\n\n");

 while (angle <= MAX)
 {
   x = (PI / MAX) * angle;
   y = cos(x);
   printf("%15d  %13.4f\n", angle,y);
   angle = angle + 10;
  }
}


Output:

        Angle        Cos(angle)
               0         1.0000
              10         0.9848
              20         0.9397
              --            ----
              --            ----
              180       -1.0000

    if(angle>=180)
    {
    break;
    }
    }
