Question

Write program to find the summation of the following series x + x³/3! + x⁵/5!+x⁷/7!......

Answer 1

Answer:

#include<stdio.h>

int main()

{

long int x,i,j,k,n,sq,cnt;

double fact,sum=0;

printf("\n ENTER THE VALUE OF N: ");

scanf("%ld",&n);

printf("\n ENTER THE VALUE OF X: ");

scanf("%ld",&x);

for(i=1,cnt=1;i<=n;i=i+2,cnt++)

{

for(j=1,sq=1;j<=i;j++)

sq=sq*x;

for(k=1,fact=1;k<=i;k++)

fact=fact*k;

if(cnt%2==1)

sum=sum+(sq/fact);

else

sum=sum-(sq/fact);

printf("\n THE SUM OF THIS SERIES IS %7.2lf\n",sum);

}

}
