<h4 class="HELM_solution">Solution</h4>
<p>The region over which we are solving Laplace’s equation is semi-infinite i.e. the \(y\) coordinate increases without limit. The solution for \(u(x, y)\) in \((5)\) will increase without limit as \(y → \infty\) due to the term \(e^{nπy}\) (\(n\) being
    a positive integer.) This can be avoided i.e. the solution will be bounded if the constant \(E\) is chosen as zero.
