First of all, I apologize if this is in the wrong place. I didn't really know where it should be placed and if it is in the wrong place I am sorry.(adsbygoogle = window.adsbygoogle || []).push({});

This question was on my recent Linear Algebra I final exam and I had no idea how to do it when I was writing the exam and I'm still stumped by it. I'm simply curious as how to go about obtaining the solution mostly because it has been bugging me for a few weeks now. Also, this is the first time using LaTeX typesetting so forgive me if it's sloppy.

Let [itex]A[/itex] be any [itex] n \mbox{ by } n [/itex] matrix.

Let [itex]S[/itex] be defined as:

[tex] \displaystyle{S=\{A|A=A^T\}} [/tex]What is the size of [itex]S[/itex] ?

Thanks in advance for any help.
