comment What is the dimension of this subspace of $M(n\times n,\mathbb{R})$
It doesn't, but it's interesting and as good an answer as this question deserves.

Would you explain this intriguing comment, Martin? If you expanded and wrote an answer I would accept it.

comment Independent undergraduate research — what to do?
You should probably be asking this question to professors in your department who can give you much more tailored advice than you will get on a website. Presumably you will have an advisor, right?

comment Tensor-free proof that for finite modules over reduced Noetherian rings, locally free = projective
Yes, I think so, but it requires proof. Locally free means that for a f.g. $A-$module $M$, at all primes $\mathfrak{p}$ in the spectrum, $M_\mathfrak{p}$ is free.

comment Easiest way to prove that an operator is linear?
In Gerry's defense I corrected it moments after he asked it. But in my defense Gerry responded too quickly, I realized my omission within seconds of posting it. :)

Ah, you are right. But you have made me realize what I was missing before, I think. It is sufficient for my purposes to just note that I can define a map from the $\mathbb{R}^{2n}$ to my set considered as a subset of the symmetric matrices. Thanks!

comment Calculation of sum
You could just add them up :) Are you asking for a closed form expression with $p$ variable? Also, it would be nice if you provided some context for where you encountered this and what methods you have tried or are available to you.

By the way that's a nice observation regarding the use of the sine identity. Folland seems to think these detours are useful as learning experiences, though. :)
