Whoops, I suppose a better way to have phrased my question was "Are there twice as many matrices whose dimensions are the same as those whose dimensions are different," but that's a great answer, thanks!

Fair to say there are "twice" as many square matrices as rectangular? Is it fair to say that there are at least twice as many square matrices as there are rectangular? I was thinking something like this... Let R be a rectangular matrix with m rows and n columns, and suppose either m < n...

Hi all, I'm trying to get into a business field that utilizes a lot of mathematics; Basically, I'm looking for a field that involves a lot of upper level mathematics (Graph theory, graduate level analysis, matrix analysis, etc.), is based in the business world, and will allow me to use...

Fractional Calculus...? What?? I came across this Wiki article a couple of days ago: http://en.wikipedia.org/wiki/Fractional_calculus As a student who just finished an undergrad major in math, the idea of a "fractional derivative" or "fractional integral" is mind blowing! Up until I read...

Homework Statement I think I've got this one about figured out, I just wanted someone to check it over. (For this problem, (a-1) is a inverse, (b-1) b inverse, etc.) "Let G be a group, H a subgroup of G. Then, H is normal in G iff every left coset of H is equal to some right coset of H"...

Hello all, I just finished my undergraduate degree in mathematics last December and I'm trying to figure out how to proceed in the future with my math degree. I am more interested in applied mathematics and am trying to get some advice as to what field to specialize in; I'm looking for...

Homework Statement I'm working on a proof for Intro. to Algebra, and the problem deals with proving that the operation of Symmetric Difference imposes group structure on the power set 2^x (set of all subsets) of a given set X. There is a part of my proof that I'd like to get some advice on...

fss - Thanks for your response, I'm very happy for the encouragement. :-) You did however point out something that I should've been more specific about... I don't intend for this to be a resume substitute, just an additional thing that I'll attach with my resume. (As well, I'm also planning to...

"Resume" website... would love some feedback! Hello to all, It's coming to be about that time when I'm going to start applying for both jobs and graduate school. Instead of just having a standard resume for jobs, I was thinking of perhaps having something a little bit more interactive and...
