Hmm I think I may have to post the question in full. My original post is just a small part of a bigger question (about Gauge transformations) so I am probably going about it wrong.
Homework Statement
I need to find Λ using the equation below (I think).
Homework Equations
A [/B]+ ∇Λ = 0
where A(x,y,z,t) = B\begin{pmatrix} x+y\\ x-y\\ 0 \end{pmatrix}
The Attempt at a Solution
Is this at all possible?
Thanks but I have probably just messed up somewhere, as I don't think it will be that much hassle.

Hi all sorry the title couldn't be more descriptive.
I'm having a bit of a brain block with this equation (it's the very end of a problem).
N(\frac{5}{6})^{N-1} > \frac{27}{5}
My line of thought was to get the first N in terms of the power N-1..
How do I find N?
