Question

WAP to print the sum of the following series S=x^2-x^4+x^6-x^8 up to n terms​

Answer 1

Question:-

Write a program to print the sum of the series.

S=x^2 - x^4 + x^6 - x^8...N terms.

Program:-

class Program

{

public static void main(String args[])

{

int n=10, x=5, a=2;

double s=0.0;

for(int i=1;i<=n;i++)

{

if(i%2==1)

s+=Math.pow(x, a);

else

s-=Math.pow(x, a);

a=a+2;

}

System.out.println("Sum of the series: "+s);

}

}

Answer 2

Explanation:

Java program to get the sum of the series

import java.io.*;

class MathSeries {

// Function to get the series

static double Series(double x, int n)

{

double sum = 1, term = 1, fct, j, y = 2, m;

// Sum of n-1 terms starting from 2nd term

int i;

for (i = 1; i < n; i++) {

fct = 1;

for (j = 1; j <= y; j++) {

fct = fct * j;

}

term = term * (-1);

m = Math.pow(x, y) / fct;

m = m * term;
