Analytical Solution to Poisson's Equation

In summary, Poisson's Equation is a mathematical equation used to describe the distribution of electric potential based on the distribution of electric charges in a space. The analytical solution to this equation is obtained by solving the differential equation using techniques such as separation of variables and integration. It has various applications in physics and engineering, but it is limited to simple and idealized systems. In more complex cases, numerical methods are used to approximate the solution.

I have the equation del^2 phi =1 for 2-d (x and y) with the boundary condition being 0 along all 4 edges. I've looked in all my math books and can't find how to solve this. If anyone could get me started I would appreciate it.

Let u= phi(x,y)- (1/2)x2. Then del2u= del2phi- 1= 0. The boundary conditions get a little complicated but it can be done as a Fourier series.

My experience with Fourier series is extremely limited and your hint doesn't mean anything to me.
