Assignment Example: Cyclic Functions


\sum_{x=1}^{5} \sum_{k=0}^{\infty} \frac{(-1)^k x^{2k-1}}{(k+x)!k!}

Block scheme of the solution:


С++ implementation:

using namespace std;
float error;
float factorial(int n)
float factorial = 1;
for (n; n>0; n--)
factorial *= n;
return factorial;
float sum = 0, item;
void main()
cout << "(-1^k*x^(2k-1))/(!(k+x)*!k)" << endl;
cout << "Input the error:"; cin >> error;

for (int x = 1; x <= 5; x++)
for (int k = 0; k <= 18; k++)//k - float overflowing border 
item = (pow(-1, k)*pow(x, 2 * k - 1)) / (factorial(k + x)*factorial(k));//calculate item 
if (error <= fabs(item))
sum += item;//summing items 
cout << setw(5) << x << setw(5) << k << setw(25) << item << setw(25) << sum << endl;//intervals & output 
cout << "______________________________________________________________overflow" << endl;
cout << endl << "sum=" << sum << endl;//output sum 
system("pause");//pause console
