Double fun (double x, int n)

Double cosx=1;
Double d=1;
For (int I=1; I & lt;=n; + + I)
{
D *=(1) * * x (x)/((2 * I - 1) * (2 * I));
Cosx +=d;

D *=(1) * * x (x)/(2 * I - 1) * (2 * I)) it didn't quite understand,

Every one is equal to it before a multiplied by (1) * * x (x)/((2 * I - 1) * (2 * I))
