    How to prepare for a math quickness/accuracy pre-interviews?

    Hello, I am applying for some jobs that have pre-interview tests. Here is one description: This is for a finance job, and I am an electrical engineering major with a pretty high gpa. So I obviously have a solid math background, but what should I expect from these kinds of tests? How...

    Easy Circuit Question

    I dunno... It just seems to me like perhaps a little bit of the current would get through. :smile: I guess if I looked at it as the current taking the path of least resistence, then yeah, I guess it's pretty intuitive. (Although, obviously, such an analogy couldn't extend to resistors in...

    Easy Circuit Question

    Is the resistance of this circuit 10 ohms? http://img75.imageshack.us/img75/9229/littlecircuitro8.jpg [Broken] I can't prove anything to myself since the resistors aren't in parallel or series. I do notice that the potential at the top of the right side resistor is the same as at the...

    Probability - Independence Question

    I think I just got more confused. :smile: Isn't the intersection of B with not-A the same as not-A? giving the fraction to be simply 1? Obviously I must be missing something, big time.

    Probability - Independence Question

    I'm trying to get the idea of independent events well grounded in my mind, but I'm having some difficulty. First of all, what would a venn diagram for independent events look like? I know you have the two events intersecting, and the intersection is equal to the product of the probabilities...

    MATLAB Just bought MATLAB

    Yeah, I finally got around to teaching myself how to code LaTex over the last few weeks, and it can't be beat. It's just awesome. I think I will even use it for non-math papers, now that I found a MLA style file. Once you get the hang of it, it's actually easier and much more efficient than...

    MATLAB Just bought MATLAB

    Well, MATLAB is explicitly required by my engineering school, so I just went ahead and got it. I'll put off any other purchases and give Maxima a try. Thanks!

    LaTeX Best Latex Editor?

    Thanks. Just tried it out and it works great!

    MATLAB Just bought MATLAB

    Thanks. Aside from typesetting, what are the differences between MATLAB/Maple/Mathematica? Are they all basically the same thing with different strength/weaknesses? Or are there any major fundamental differences?

    MATLAB Just bought MATLAB

    I just bought MATLAB because it is absolutely required at the university I will be attending in the fall. While I've only given MATLAB a quick overview, it seems that it's probably not something I would be able to use for writing papers. It also doesn't look very efficient for quick graphing...

    LaTeX Best Latex Editor?

    What's a good freeware latex editor? I've been trying to install LEd, but it's not going smoothly, so I don't want to waste anymore time if it's not worth it. Any suggestions?

    Schools What do you do in Grad school?

    I just thought of another question... I remember a while back someone told me that you have to learn to read/write a mathematically relevant foreign language (German/Russian/French, any others?) in order to get a PhD in math. Is this true? I'm sort of hoping that it is. I'd really like to...

    Schools What do you do in Grad school?

    How about courses on the history of mathematics if you are a math major? (do they even use the term "major" when talking about grad students?) That's something that has always interested me. Would it be easy to take those courses? I obviously have very little knowledge about grad school, so...
