Hello,

Thanks at first. If anyone can understand, then I would like to know how do I get to equation 4.15. Its a laplacian equation in which I want to apply the Fourier transform.

Thanks again.

It seems that they are evaluating the integral directly using the calculus of residues from complex analysis.

Thank you for your reply. Could you kindly tell me where to look for to get to this solution.
Thanks again.

I sketched the isoclines for $$ m=-1,0,1,2 $$. Since both $$ \frac{dy}{dx} $$ and $$ D_{y} \frac{dy}{dx} $$ are continuous on the square region R defined by $$ -4\leq x \leq 4, -4 \leq y \leq 4 $$ the existence and uniqueness theorem guarantees that if we pick a point in the interior that lies on an isocline there will be a unique differentiable function (solution) passing through that point. I understand that a solution exists but I unsure how to actually sketch it. For example, consider a...
