GRE subject testI've started studying for the Math GRE subject test today, you can click here to download a practice test. 1/2 of it is only introductory calculus, the other half on Algebra, Number Theory, Combinatorics, Multivariable Calculus, Differential Equations, Linear Algebra, and even some Topology and Vector Calculus thrown in there. Some of them are fairly tricky. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #2 20070620 16:30:21
Re: GRE subject test64 questions in less than three hours? And all of them quite different. That is one tough exam! "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #3 20070620 16:43:46
Re: GRE subject test
66. I finished and calculated my score in just over 2 hours, but a lot of problems I guessed on and didn't go back to like I would have while taking the actual test. Got a 700, so not horrible for the first try. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #4 20070621 02:29:05
Re: GRE subject testIs the answer to 63 . All the other questions on the test are hard! You must have to be a polymath to do well on that.#5 20070621 03:12:01
Re: GRE subject testThere's a mark scheme with all the answers on page 56 of the PDF. Why did the vector cross the road? It wanted to be normal. #6 20070621 05:34:00
Re: GRE subject testNope identity, you gotta add one more. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #7 20070621 06:13:56
Re: GRE subject test60 is another one that I tried to take an educated guess on and got wrong. But it becomes amazingly easy if you start at the top and work your way to the bottom. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #8 20070622 01:26:40
Re: GRE subject test
But how??? #9 20070622 02:31:05
Re: GRE subject testx¹² is eventually taken over 2^x. You can see this by comparing their derivatives. It happens at a fairly high number, but none the less, it happens. And when it does, there is a third intersection. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist.

Re: GRE subject testOh I see, too bad the 'solve' command only gives 2 solutions >.< #11 20070622 06:18:31
Re: GRE subject testIt does so because there is no general algebraic way to solve an equation with 2^x. All other methods like guess and check only work if you know where to guess. So the solve function will guess values and compares the distance between the two functions. x¹² = 2^x tricks the solve feature because it starts getting further from each other, and then after a while gets closer.

Re: GRE subject testWhen are you taking it? I need to take mine very soon as well. #13 20070622 07:43:03
Re: GRE subject testI'm still not certain. The last month I can really take it in is October. But I'm hoping to take it in August so I have 2 more chances to take it if I screw something up. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #14 20070622 12:31:13
Re: GRE subject testSounds like a good plan. It's nice to have extra chances if you feel that you didn't prepare yourself well enough the first time around. I don't think that anything I'm taking this coming semester will help me too much on the exam, so I'm thinking about taking it in August too, and possibly a retake if I feel that I could have done better. My only problem is that I need to figure out if I'll be at home or at school when the test is administered. I'll probably be at school for TA training though. I think I have about 2 weeks still before I need to be certain of that so I can register by the deadline. #15 20070623 14:35:28
Re: GRE subject testOn the test, there seem to be a lot I can solve, but I wouldn't be able to if it wasn't multiple choice. For example, 31. If I assume that 1/4 is a root of the polynomial, it becomes fairly easy to show that it must be 2^4  3^2 + 2^10b, which is impossible. But is there another way to do this problem?

Re: GRE subject testhi everybody. Check this out. #17 20070723 07:40:08
Re: GRE subject testYou should make your own topic for this question rather than put it on top of someone else's. Why did the vector cross the road? It wanted to be normal. #18 20071107 13:18:52
Re: GRE subject testRicky. Sorry for digging up this old topic but I was just interested in it. Did you actually take the GRE? How did you do? I am just a freshman right now doing a Math major and Im just taking Calculus I and I was fairly intimidated by that test...I hope the next 4 years of math classes prepare for it. #19 20071108 04:47:13
Re: GRE subject testI did actually just take it not more than 4 days ago. It was fairly difficult although I feel I did quite well. I have to wait till mid December to find out though. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #20 20071108 04:58:12
Re: GRE subject testHehe. I guess we are similar. I behave the same when taking tests or doing something that requires my total attention. Its like, my mind is totally concentrated on what im doing but its like my body starts moving to relieve the stress, like I start bumping my legs, making weird faces etc. :p #21 20071108 08:12:13
Re: GRE subject testWow, thanks! I am an undergrad attending Virginia Tech majoring in math and computer science. Hopefully I'll be graduating this spring and get into a PhD program next year, but I'm still almost completely clueless as to which I want to attend. "In the real world, this would be a problem.

Re: GRE subject testI see. Im still a freshman so i got a long way to go but hey, I heard time flies in college. #23 20080402 03:47:12
Re: GRE subject testSo here i am just digging up your post again.
