This Demonstration plots the solution to Laplace's equation for a square plate, .


The solution is given by


where and are the length and height of the plate (here ) and


where .

You can vary the temperature along the left edge. As you increase the number of terms , observe the Gibbs phenomena at the corners and along the edge where the temperature is higher.
