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...
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...
Is the resistance of this circuit 10 ohms?

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...
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.
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...
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...
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!
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?
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...
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?
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...
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...
Thanks guys.
Another thing: Are you expected to get lots of papers published in journals while working on your PhD?
Is this phase of the program a solitary one? Is there some sort of arrangment where you discuss your research with supervisors on a regular basis? Or are you just let...
O.K. This question shows just how ignorant I am about things academic, but what do people working on a PhD do? And how long does it take to get your PhD?
I'm mainly interested in knowing about a PhD in mathematics. Here are my questions:
1)Do you take only classes that relate to math...
blue,
Just start with your math where you feel most comfortable. I started with arithmetic when I was 22 years old, and I just chugged along. Don't ever think you aren't a "math person" either... That's all b.s. American schools screw us over mathematically, and we think we suck at math...
This is exactly what I needed. I've seen that trick a handful of times, but I always forget it when I need it! :biggrin:
Thanks Orthodontist.
BTW, this reminds me of a side question. I call the above a "trick" because I think of it as multiplying the derivative by 1=dr/dr... But is that...
This problem has me stumped:
If r = (x^2 + y^2)^{1/2}, show that
div \left( \frac{h(r)}{r^2}(x \vec{i} + y \vec{j}) \right) = \frac{h'(r)}{r}
My trouble is with mixing the polar coordinates with the position vector. If I write the above as
div \left( \frac{h((x^2 +...
I'm trying to get a handle on seeing whether a vector field (in the x-y plane for simplicity) has zero divergence at a point or is divergence free altogether. I'm having some trouble with this.
The way I am thinking about it is to mentally draw a little box around my point and then see...
It's hard to answer this because I have no idea what school you are at, nor what your curriculum is like. So take what follows with a grain of salt.
It's mainly problem solving. In the calc based physics offered at my school, the only thing we ever did was solve word problems (some straight...
Yes, this is what worries me most. For that reason, I don't think I will abandon EE. But I'm starting to think more seriously about a double major: pure math and EE. I'll finish a year late, but that's o.k. with me.
That's probably true. But I have been exposed to a lot more than my...
Thanks, Maxwell. I think I will find EE interesting enough to get through the program. I definitely don't hate it, and it's nice to know that circuits don't stay boring. I also think there's a good chance that I'll love it once I take a couple of good classes.
Thanks again!
Maxwell (Very electric name, btw :biggrin:)
The only exposure I've had to what EE might be like is my Electricity and Magnetism class. I've taken no actual engineering classes yet.
I love Gauss' law, ampere's law, Faraday's law, magnetic fields (particle accelerator problems and stuff)...
