Re: Linear Interpolation FP1 FormulaUnlike adriana my performance in STEP won't affect whether or not I go to UCL, but realistically I think I will get at least S, 1 and 2 in STEP I, II and III. I would like to get 3 Sgrades, but that will take some more work. It is very difficult to get an S in STEP III. #10077 20130414 23:22:36
Re: Linear Interpolation FP1 Formula66 days away you say? That is plenty of time. 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. #10078 20130414 23:25:34
Re: Linear Interpolation FP1 FormulaYes  although it is hard to complete a whole paper in one day... #10079 20130414 23:32:00
Re: Linear Interpolation FP1 FormulaIf I can help just post it. 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. #10080 20130414 23:35:14
Re: Linear Interpolation FP1 FormulaIt is OK at the moment, for 20042012 they provided solutions  although for 2003 and beyond they didn't include them. #10081 20130414 23:38:05
Re: Linear Interpolation FP1 FormulaThat may be your opportunity. Do not volunteer, let her ask. 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. #10082 20130414 23:41:17
Re: Linear Interpolation FP1 FormulaSometimes she asks for help, sometimes we do a question together. She needed help on a geometry question and I couldn't help her with it because it puzzled me too. #10083 20130414 23:46:03
Re: Linear Interpolation FP1 FormulaThat is what a CAS is for. 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. #10084 20130414 23:49:19
Re: Linear Interpolation FP1 FormulaIt would be nice to use one, but not for this exam, it is not permitted. No calculators. In fact I heard they ban measuring instruments/compasses/etc. too. Pen and paper. #10085 20130414 23:52:56
Re: Linear Interpolation FP1 FormulaI meant for checking right now. 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. #10086 20130414 23:56:41
Re: Linear Interpolation FP1 FormulaThey provide solutions thankfully, so no need to use them for STEP. I use them occasionally though but only for simple things like patternspotting, like when you got me to work out the coefficient of x^{n} in the expansion of (1 + x + x^{2} + ... )^{k}, which was (n + k  1) C (k  1). That one has been very useful. #10087 20130415 00:02:05
Re: Linear Interpolation FP1 FormulaYes, that was a good problem. 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. #10088 20130415 00:12:02
Re: Linear Interpolation FP1 FormulaAlso, if G(x) is some generating function, is it always true that would this kind of thing work? #10089 20130415 00:12:56
Re: Linear Interpolation FP1 FormulaThe last bit of LaTeX should be differentiating the GF, setting equal to 1, and getting 3.5, the correct answer. #10090 20130415 00:22:43
Re: Linear Interpolation FP1 FormulaYes, you can get all the moments from the generating function. 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. #10091 20130415 00:32:25
Re: Linear Interpolation FP1 FormulaDo the moments have any meaning for nonprobability GFs? Combinatorial problems for instance? #10092 20130415 00:33:46
Re: Linear Interpolation FP1 FormulaI do not think so, A probability GF is different. 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. #10093 20130415 00:36:48
Re: Linear Interpolation FP1 FormulaOh, okay. STEP III has some generating function questions, I didn't know they came up in STEP. #10094 20130415 00:43:20
Re: Linear Interpolation FP1 FormulaThey are slowly working their way into every level of mathematics. 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. #10095 20130415 01:37:24
Re: Linear Interpolation FP1 Formulaadriana doesn't seem to get them at all unfortunately... maybe it is the way I am explaining it. #10096 20130415 01:39:33
Re: Linear Interpolation FP1 FormulaThey can be a bit difficult to get at first but once you do... 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. #10097 20130415 01:47:37
Re: Linear Interpolation FP1 FormulaI found them difficult at first too, I still find them a bit tricky, they are very powerful though. #10098 20130415 01:51:22
Re: Linear Interpolation FP1 FormulaThey are a lot of fun too. 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. #10099 20130415 01:55:56
Re: Linear Interpolation FP1 FormulaSpeaking og GFs, bobbym, have you been able to get through the 3rd chapter of GFology? 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 #10100 20130415 02:03:17
Re: Linear Interpolation FP1 FormulaAbsolutely not, it is said Wilf could not get through it. 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.
