Question

It is my question :

how to write the formula of hoarmnic numbers in vba {1+1/2+1/3+1/4+....)

the sum is 10 and i would like to find the terms .....

thanks for your help

Another question :

thanks for your reply. How about the solution in visual basic?

thanks a lot

Answer #1

**First Question :**

You don't need to write the formula. Simply use for loop and a variable of double type to add the values in to your final sum. Please find below program to understand it more.

**Second Question :**

Below is the program to find out sum of first n harmonic terms.

```
using System;
public class Exercise19
{
public static void Main()
{
int i,n;
double s=0.0;
Console.Write("\n\n");
Console.Write("Calculate the harmonic series and their sum:\n");
Console.Write("----------------------------------------------");
Console.Write("\n\n");
Console.Write("Input the number of terms : ");
n= Convert.ToInt32(Console.ReadLine());
Console.Write("\n\n");
for(i=1;i<=n;i++)
{
Console.Write("1/{0} + ",i);
s+=1/(float)i;
}
Console.Write("\nSum of Series upto {0} terms : {1} \n",n,s);
}
}
```

For the sequence 8x + 4, 7x + 3, 6x + 2, 5x +1, ... ,
a. Identify the next 3 terms.
b. Is the sequence arithmetic or geometric? How do you know?
c. Find the explicit and recursive formulae for this
sequence.
d. Write out the sum formula for the first 20 terms and
evaluate.
e. Write your process to part (d) in Sigma Notation.

I'll get a question like the one below and my professor says
that we need to find all three equivalence points in order to know
what stage we are in. I know how to find the first equivalence
point, but I don't know how to find the 2nd and 3rd equivalence
point.
Please show me how to calculate
all equivalence points for the problem below. Thanks for your
help!!!

Use C++
Write a program that first reads in how many whole numbers the
user wants to sum, then reads in that many whole numbers, and
finally outputs the sum of all the numbers greater than zero, the
sum of all the numbers less than zero (which will be a negative
number or zero), and the sum of all the numbers, whether positive,
negative, or zero. The user enters the numbers just once each and
the user can enter them...

Another for me would be the right to kill any...
