Re: Problems and SolutionsThat's an interesting one. I think it's something like this: Why did the vector cross the road? It wanted to be normal. #378 20060112 03:16:41
Re: Problems and SolutionsI'm not sure, this is what I get: Last edited by Ricky (20060112 03:16:58) "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..." #379 20060112 04:09:16
Re: Problems and SolutionsI think our answers are the same, and I've just taken a long way round. Why did the vector cross the road? It wanted to be normal. #380 20060112 07:34:24
Re: Problems and SolutionsYea, I guess they are. They looked completely different at first glance. "In the real world, this would be a problem.

Re: Problems and Solutionsdarn that k+42, I just cant figure it. Please someone, put me out of my misery. I think that you have to incorporate a geometric series somehow, but everything that I try turns to nonsense. #386 20060115 11:47:28
Re: Problems and SolutionsYes, k+42 is an incredibly difficult one. I think it could probably be solved brutally by getting excel to do all the calculations for you, but it's still tough. Why did the vector cross the road? It wanted to be normal. #387 20060115 15:12:47
Re: Problems and SolutionsI didn't check if this one has already been solved, but since irspow asked about it, I gave it a go. Last edited by ryos (20060115 15:15:25) El que pega primero pega dos veces. #388 20060115 16:13:17
Re: Problems and SolutionsFour days Pongal break, and so many solutions posted! I shall reply to all of them after I return from Holiday on Jan 16. mathsyperson is right, irspow's solution to problem # k + 40 isn't correct. It is much smaller. . Same about ryos' solution to problem # k + 42. Character is who you are when no one is looking. #389 20060116 16:02:39
Re: Problems and Solutionsirspow's solution to Problem # k + 59 is correct. I shall wait for some more time before posting the solutions to unanswered problems. Character is who you are when no one is looking. #390 20060116 16:11:31
Re: Problems and SolutionsProblem # k + 86 Character is who you are when no one is looking. #391 20060116 16:42:03
Re: Problems and SolutionsExcellent, irspow's solution to problem # k + 48 is correct too! Character is who you are when no one is looking. #392 20060117 09:19:05#393 20060117 18:36:28
Re: Problems and SolutionsWell done, irspow Character is who you are when no one is looking. #394 20060215 01:08:05

Re: Problems and SolutionsI made a mistake while posting problem # k + 87. Character is who you are when no one is looking. #397 20060216 02:11:01

Re: Problems and Solutions
Ah. That makes more sense. I thought there was a mistake somewhere because as it was, the proof was really obvious, so it didn't seem sensible. I've got a vague idea for k+88, but I'll wait for it to mature a bit more before posting it. Why did the vector cross the road? It wanted to be normal. #400 20060216 10:45:49
