Question

WAP in java to find the sum of the series x+(x^2/2)+(x^3/3)+(x^4/4).....(x^n/n)

Answer 1

Answer:

import java.util.Scanner;

public class SeriesSum

{

  public static double calcSeriesSum(int x, int n)  

  {

  double i, total = 1.0;

  for (i = 1; i <= n; i++)

  {

      total += (Math.pow(x, i) / i);

  }

  return total;

  }

   

  public static void main(String[] args)  

  {  

   Scanner sc=new Scanner(System.in);

   System.out.print("ENTER A NUMBER: ");

   int x =sc.nextInt();  

   System.out.print("ENTER THE NUMBER OF TIMES THE SERIES SHOULD BE EXECUTED: ");

   int n = sc.nextInt();  

   System.out.printf("%.2f", calcSeriesSum(x, n));  

  }  

}
