Question

write a java program to compute and print the sum of the following series S=x/2-x^2/4+x^3/6-x^4/8+...+x^n/2n​

Answer 1

Answer:

Program:-

import java.util.*;

public class Series

{

public static void main(String args[ ])

{

Scanner in=new Scanner(System.in);

int a,n,x;

double s=0.0;

System.out.println("Enter x");

x=in.nextInt();

System.out.println("Enter n");

n=in.nextInt();

for(a=1;a<=n;a++)

{

s=s+(double)(Math.pow(x,a)/2*a);

}

System.out.println("The sum of the given series="+s);

}

}
