2) The program calculates cosines values for angle 0,10,20.......180 and prints out the results with headings.
#include <math.h>
#define PI3.1416
#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;
}
getch();
}
Output: Angle Cos(angle)
0 1.0000
10 0.9848
20 0.9397
30 0.8660
40 0.7660
50 0.6428
60 0.5000
70 0.3420
80 0.1736
90 -0.0000
100 -0.1737
110 -0.3420
120 -0.5000
130 -0.6428
140 -0.7660
150 -0.8660
160 -0.9397
170 -0.9848
180 -1.0000
