### Re: An inspiring mathematician

In my opinion, Terence Tao is a fantastic teacher of mathematics.

### Re: Minimisation, ordering and xkcd#173

Well, the stable marriage problem would just match people up as pairs. This would give you information, in terms of the movie theater, as to who should sit next to each other, but it wouldn't give you any information about where those people would then sit in the theater. Also, using the stable mar...

### Re: Minimisation, ordering and xkcd#173

Would it be altogether unreasonable to use the stable marriage problem as well? I realize it's not possible to rank people equally, but it could provide some interesting results.

### Re: Animating Geometry

I have a friend around here that does a lot of somewhat heavy geometric visualization using Mathematica. I'm not involved in the research, so I'm hazy on the details, but you might consider that route. From what I understand its somewhat of an upfront investment to learn Mathematica's animation com...

### Animating Geometry

So, here's the deal fellow xkcd denizens. I'm currently involved with a hyperbolic geometry research group on campus (undergraduate research), and we're studying isometries in PSL(2,R) / SU(1,1). The question I have doesn't necessarily require any knowledge about these objects, so don't be too conce...

### Re: Help with volume integrals

The primary difference between the two is that a double integral over a function will result in something that can be interpreted as a volume, while a triple integral is generally one dimension higher (i.e. - integrating a function involving density to find the mass of the object in question). Howev...

### Re: Which math should I take next year?

The linear algebra recommendation that has been given ad nauseam so far is certainly a good one. I was fortunate enough that the course offered here was a service course for other disciplines, but focused equally on it's applications as well as more abstract proofs. It's a great course for anyone wh...

### Re: Scared for Integrals and Trigonometry

Be sure, when doing rotational solids, that you indicate what axis you're rotating around, and slice your area appropriately.

Yeah, we -just- went over using determinants to find eigenvalues in our lecture today. Thank you for your responses!

### Linear Algebra (easy) Question

So, I was working through my Linear homework this morning, and stumbled upon this problem, I'm fairly confident I understand the principles in question here, but I was hoping you guys could have a look see and let me know if I made any errors: For: A_{3,3} \begin{bmatrix} 1 & 2 & 3 \\ 1 &...

### Re: Calculus II Question

Yes, I do understand the conversion factor, something along the lines of \,w = 1-2z\, dw=-2dz dz=-1/2dw And there was another page or so of scribbling done on my scratch that i'm just too lazy to put into LaTeX (and wasn't the point i was getting stuck on). However, my question is, with the change o...

### Re: Calculus II Question

So, with the limits being from 1 to -1 with respect to w, we would have: \,5\int\limits_{1}^{-1}\,h(w)\,dw and reversing the limits would produce: \,-5\int\limits_{-1}^{1}\,h(w)\,dw Which, while having the same limits as h(z) still leaves me perplexed as to what to do, and geometrica...

### Calculus II Question

Okay, so I had a test in my Calc II course yesterday, and all went fairly well and routine until I stumbled upon this problem: Assume \int\limits_{-1}^{1}\,h(z)\,dz=7 Calculate \int\limits_{0}^{1}\,5h(1-2z)\,dz Now, this may be easier than I think it is, but I don't remember covering...
