# Math Translation

Posts: 15
Alright, I just received a homework assignment involving convergence loops. The problem is, I haven't taken any overly-advanced math classes yet, so I have absolutely no idea what this means:

*Note that variable a is a user-defined integer.

Could someone please translate that to a Java formula? I can't even really begin to attempt this homework without knowing what that means.

I'll try to explain in plain English what the math expression means.

You start with i = 0, and with a value x(0), and a constant value a.

Then you calculate the next value of x: x(1) (with i = 1). You do this with the given formula:

x(1) = (2 * x(0) * x(0) * x(0) + a) / (3 * x(0) * x(0))

Do you see how that matches with the math formula?

Then, when you have x(1), you can calculate x(2) using x(1), then x(3) using x(2) etc. as far as needed.
