Re: Another coin problem12 is correct. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #77 20130328 02:57:34
Re: Another coin problemIs the other one asking for the probability of there being a pair of cards with the same suit? The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #78 20130328 02:58:55
Re: Another coin problemYes, same as the other question. Adjacent cards are of the same suit. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #79 20130329 18:52:34
Re: Another coin problemHow to solve it? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Another coin problemSolve it? By analytical methods, no way! In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #81 20130329 19:29:01
Re: Another coin problemWhat are analytical methods? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Another coin problemThe methods of mathematics. They actually only solve a very limited set of problems. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #83 20130329 19:45:50
Re: Another coin problemReally? I thought they solve all problems. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Another coin problemThe methods I have been trying to pound into anonimnystefy, zetafunc and you. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #85 20130329 19:50:07
Re: Another coin problemSorry but I do not know what you are talking about 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #86 20130329 19:52:40
Re: Another coin problemHmmm, geogebra and programming are two non mathematical methods to get answers to problems when the math fails to.
So did I... It seems that way to you now because you are never given a problem in school that they do not solve. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #87 20130329 19:54:35
Re: Another coin problemBut geogebra does it internally with math and programming 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #88 20130329 19:56:44
Re: Another coin problemSomewhat but it may also use iterative algorithms and lots of computation. In industry you will face many more problems that do not have nice clean book answers. They still need to be solved! In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #89 20130329 19:58:19
Re: Another coin problemIn industry of what? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #90 20130329 20:02:17
Re: Another coin problemLets say a corporation that manufactures metals for aircraft or something connected with the military or defense. Something like that, the math will be very different from what they teach in school. School actually gives students many wrong impressions about what can be solved and what can not. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #91 20130329 20:12:24
Re: Another coin problemBy the way, What is gcse level math? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #92 20130329 20:13:06
Re: Another coin problemIt is I believe something to do with math in England. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #93 20130329 20:29:18
Re: Another coin problemIs it very tough? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #94 20130329 20:36:48
Re: Another coin problemThere is a simple rule that they are hiding from everyone that answers that question. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #95 20130329 20:37:50
Re: Another coin problemSo what the rule is? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #97 20130329 20:52:38
Re: Another coin problemDoes it mean you have already taken gcse? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #98 20130329 20:55:59
Re: Another coin problemNope, I live in the US and have never even heard of GCSE. I thought you were talking about non  mathematical methods. I am sorry for the confusion. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #99 20130329 21:16:32
Re: Another coin problem
In England, you take GCSEs when you are 1516. It is the highest level of compulsory education. GCSElevel maths shouldn't really be a problem for you; if you are able to solve the geometry/number theory/etc. problems you have been posting, it won't be much trouble. The spec is pretty broad as I remember it, there isn't any mechanics but there is a bit of stats. Google GCSE Edexcel Maths (Linear) for an idea of what the level would be like. Typically the course is studied over two years but it can of course be done a lot quicker if you know much of it already. #100 20130329 21:39:10
Re: Another coin problemNo, we do not have GCSE in India. Atleast I don't think so. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'
