### does there exist a math analogue of grephysics.net?

hi fellow math-lovers--

Last fall I took the physics GRE and found the awesome resource grephysics.net, where the solutions to all four of the publicly available practice exams had been written out and posted. Now I'm gearing up to take the math GRE this fall, and am wondering if there is any website out there that does the same for the math subject GRE?

If not, then could someone please explain (formally) why E is the answer to #26 on exam 8767? =) I can _almost_ convince myself of it qualitatively, but I'd like to know what the true solution is.

(I may have a few of these questions while I work through all four available math practice exams, so please redirect me if I am not posting in the right place, or if there is already a designated thread for one-off solution requests, etc.)

This forum was created by the founder of physicsgre.com. Steadily, there is idea to create from this forum the web-resource, similar to that of physics students. At least this year the idea is to make list similar to http://www.physicsgre.com/results.php if people on this forum help to contribute to it. I myself haven't seen any resource better than this forum for the math subject preparation.

As for #26 in 8767, every point (0, k), where k is in [-1,1] will be the limit point of the set sin(1/x). Therefore, to make it disconnected, we need to move k "outside" this interval.

We could build something like this here. Apparently ETS doesn't mind people referencing the publically available problems. I am able to setup an organized structure referencing all the publically available problems and then everybody can solve the ones they can and eventually we would have multiple solutions to all problems. I also want to implement the results concept lime mentioned above. I guess the only question is which should be give a higher priority "solutions system" or "application results"?

I certainly vote for "application results". That would be just perfect to have such statistics to let perspective applicants get the orientation in the score range they should orient for. If that is possible, can we also include in this table the column for the TOEFL score? That would be also very helpful.

As for "solution system" - it is also good idea, but not really of high importance, since basically all difficult problems from preparation books already have been discussed here and can easily be found using search.
