Write a C program to calculate the following sum: sum = 1 – x2 /2! + x4 /4! – x6 /6! +x8 /8! – x10/10!

Write a C program to calculate the following sum:

sum = 1 – x2 /2! + x4 /4! – x6 /6! +x8 /8! – x10/10!

Program Code:

#include<stdio.h>

#include<math.h>

void main()

{

int i = 2, n, s = 1, x, pwr = 1, dr;

float nr = 1, x1, sum;

printf("\n\n\t enter the angle...: ");

scanf("%d", &x);

x1 = 3.142* (x /180.0);

sum = x1;

printf("\n\t enter the number of terms...: ");

scanf("%d", &n);

While ( i <= n )

{

pwr = pwr + 2;

dr = dr * pwr * (pwr - 1);

sum = sum + (nr / dr) * s;

s = s * (-1);

nr = nr * x1 * x1; i+= 2;

}

printf("\n\t the sum of the sine series is..: %0.3f",sum);

}
