Write a program in C to computer the sine series

Answer»

#include

int MAIN()
{
int i, j, n, fact, SIGN = - 1;
float x, p, SUM = 0;

printf("Enter the value of x : ");
SCANF("%f", &x);
printf("Enter the value of n : ");
scanf("%d", &n);

for (i = 1; i <= n; i += 2)
{
p = 1;
fact = 1;
for (j = 1; j <= i; j++)
{
p = p * x;
fact = fact * j;
}
sign = - 1 * sign;
sum += sign * p / fact;
}

printf("sin %0.2f = %f", x, sum);

return 0;
}


The output will be:
Enter the value of x : 2
Enter the value of n : 3
sin 2.00 = 0.666667
