Solving Four Elliptic Partial Differential Equations Using the Finite Element Method by James Pate Williams, Jr.
The equations I solve in this blog entry are from a thesis that uses artificial neural networks to solve partial differential equations:

Here are the equations snipped from the thesis:
Alpha is defined as 0.5 * n. In our case n = 1, 2, 3, 4.
The solutions for the four cases above are graphed using Microsoft Mathematics:
