comment How do I obtain an appropriate energy functional from the weak formulation of a partial differential equation?
Substituting v=u into the weak formulation accounts for most of the functional $F(u)$ except for the term $\frac{1}{2}au^2$. Where did the $\frac{1}{2}$ come from?

@shoda: Yes, you are correct. In the process of copying and pasting, I neglected to change the limits. Thanks for the heads up! :)

comment Help solving differential equation
There are a variety of ways to solve it. Are you looking for an analytical solution or a numerical one? Also, have you consulted any introductory ordinary differential equations books? This is a classic problem with well studied properties and I'm sure you can find more detailed information in a good undergraduate textbook.

comment Understanding how to state the Karush-Kuhn-Tucker Conditions for a given problem
Actually, I just read the errata: users.eecs.northwestern.edu/~nocedal/book/2ndprint.pdf It says that $\frac{1}{8}$ should be replaced by $\frac{1}{2}$ in the objective function. I'll make the edit.

You're right... I copied it from the text, so I guess there's a slight mistake there.

comment Is the product of square singular and non singular matrices always singular?
That's exactly what I was thinking of, intuitively... I just needed a way to justify it analytically.

comment How do I combine two matrix equations into one?
Perhaps this would be best addressed in the Computational Science Stack Exchange (scicomp.stackexchange.com).
