Question

Write a program to find the sum of the following series:

`x  – x^2/(2!) + x^3/(3!) + x^4/(4!) + x^5/(5!) – x^6/(6!)`

Answer 1

using namespace std;
#include
int main()
{
int i,x,n,f=1,sign=1;
float sum=0,t;
cout<<“\nEnter N value”;
cin>>n;
cout<<“\nEnter x value …”;
cin>>x;
t=x;
for(i=1;i<=n;i++)
{
f = f * i;
sum = sum + sign * t/f;
t = t * x;
sign = -sign;
}
cout<<”SUM OF THE SERIES = “<<sum;
return O;
}

Output
