Post your answers as a link, like this, so when you hover over the link, you can view the answer. This should give everyone a chance to try the problem if they'd like to. -- Jai .  -  16:41, May 22 2012 (UTC)
 * Cant you put a different page for answers only? It could get messy if you let the answers and the discussion together [[Image:SilentSign.png|x19px|link=User:Silent]] 17:39, 22 May 2012 (UTC)

Dear Jaigoda:
Is this in fact a cunning way to crowd source/check answers to your homework assignments? I tend to assume these problems always have some nasty trick when someone posts them, but so far, that has not been the case. A new misery 17:33, 22 May 2012 (UTC)
 * "Jai, have you done your homework?" "Dont worry prof. theyre on my PvX account" [[Image:SilentSign.png|x19px|link=User:Silent]] 17:36, 22 May 2012 (UTC)
 * What kind of a noob teacher would set questions directly from the internet? Cɥıǝɟʇɐıu Alǝx  18:17, 22 May 2012 (UTC)
 * My university lecturers did, even in 3rd year quantum physics, although, to be fair there are only like 12 problems you can solve without a computer there... I hadn't done a search, I would assume Jaigoda to be capable of changing the numbers or wording, but apparently not ^_________^ A new misery  18:31, 22 May 2012 (UTC)
 * Uhh, if you want to do some homework for me, I can give you some differential equation problems! ^_^ And yeah, the questions so far have been pulled directly from google. -- Jai .  -  18:34, May 22 2012 (UTC)
 * Pretty much every prof teaches out of the same 2-3 texts books for EM/quantum/GR so solutions are everywhere online (and most profs are too lazy to make up their own problems once, let alone from year to year).--TahiriVeila 19:02, 22 May 2012 (UTC)
 * Wow, you're lucky. My teachers of Algebra and Geometry make problems by their own and even fail...--Sewa 19:26, 22 May 2012 (UTC)
 * Algebra and Geometry are super easy to make problems for. Hell, when I tutor kids I usually just make up my own. higher-level math and science is a different story. -- Jai .  -  20:33, May 22 2012 (UTC)
 * Well, university Algebra is not so easy --Sewa 07:14, 23 May 2012 (UTC)
 * Not to talk down to you in any way, but it doesn't seem like that anymore now that I'm taking Calc and Diff Eqns. It's all a matter of perspective, though, as geometry used to be really tough for me and now it feels like a cakewalk. -- Jai .  -  01:16, May 24 2012 (UTC)

Difficult problems
Not difficult, more like long. Try to do longer problems or we'll finish them in 1 hour at most and youll need to do one every day :) Silen†  11:03, 25 May 2012 (UTC)
 * I'll see if I can't find a good one this weekend. -- Jai .  -  13:55, May 25 2012 (UTC)

yup that's some calculus-- Relyk 06:26, 29 May 2012 (UTC)
 * Umm, it's actually really easy and stupid... Relyk's answer is correct, but the first term isn't actually a limit at all, you can simply substitute 2010 for x and the integration is almost the easiest integration you can do. You just need to rearrange it to 4040100.x^-2, then use the rule that the integral of n.x^c = (n.x^(c+1))/(c+1). That is the first integration rule you learn ever. I suppose the one piece of knowledge you require is that 1/infinite = 0. I'm not sure what you are aiming for here Jai. I guess you won't set any problems you can't do yourself, what level of math have you studied? A new misery  07:51, 29 May 2012 (UTC)
 * math is srs bsns on pvxwiki-- Relyk 08:49, 29 May 2012 (UTC)
 * Calc 2, taking Diff. Eq. And yes, I know it's a pretty easy problem if you still remember calc. Don't take it seriously, they're not meant to be ball-buster problems. --jī·gō·dǔ -  11:07, 29 May 2012 (UTC)
 * I think my problem is I spend too much time hanging around Tab and Mafaraxas and they are always like "So if you take the curl of this motherfucker and then apply the squeeze theorem, you get this simple 14 term non-linear differential equation and then it is trivial to arrive at a cute mcmonkey!" A new misery  11:54, 29 May 2012 (UTC)
 * See, problem is, there are plenty of people who haven't taken higher level math. I'd say the most I'd be able to realistically assume would be precalc. So if I'm going to make a problem where a good amount of people can solve it, it has to be pretty simple, though I've been trying to pick some stuff that's challenging and/or cute. Though if you know some physics 2, Mis, try this one out. jī·gō·dǔ -  15:42, 29 May 2012 (UTC)

Remind me later today and i'll find some fucking awful contour integral for you to do misles.--TahiriVeila 09:06, 29 May 2012 (UTC)
 * The irony is, then I won't do it ^_____________________________^ A new misery  09:31, 29 May 2012 (UTC)

if you're in college, you should try jamming with the Putnam team then tell us about it. &#9823;Fianchetto 16:48, 29 May 2012 (UTC)

Now that everyone's already done this problem who wanted to, I'll tell you where I got it. In my senior year I signed up for this NASA program where you did a bunch of crap in an "online learning community" and the ones who participated the most would get a summer internship with NASA (I never ended up doing anything :P). They held a contest to make a logo for the program, and the one that won was this. It wasn't until like the day I posted this that I actually got around to trying the problem out, and I found it cute enough to add here. But yeah, chances are the person who made it hadn't taken much more than AP Calc or something. jī·gō·dǔ -  12:40, 31 May 2012 (UTC)

Finding the time taken and differentiating it gives this for me.-- Relyk 23:55, 8 September 2012 (UTC)

I do this when walking across a street sometimes, I will want to walk at a bigger angle as possible to reduce time, sadly cars drive on roads and my mission is often aborted. Frostels 20:20, 9 September 2012 (UTC)
