Discussions About The FormulasYou can discuss general matters about the formulas here. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20060405 02:29:56
Re: Discussions About The FormulasI think that once a formula is submitted, a moderator should copy and paste it into the first post of the topic, and in doing so, we are able to organize these into sections to make it easier to read. "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..." #3 20060405 04:52:08
Re: Discussions About The FormulasI totally agree! I was actually going to post this suggestion myself.. #4 20060410 02:55:17
Re: Discussions About The FormulasGreat new forum, MathsIsFun! A logarithm is just a misspelled algorithm. #5 20060410 07:37:27
Re: Discussions About The Formulas
Do you mean that each topic will have only one post? "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #6 20060410 09:10:07
Re: Discussions About The FormulasI would say they should all go within in post. But that's just an opinion, nothing more. I don't have any real reasoning as to why one post rather than many. "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..." #7 20060418 14:52:13
Re: Discussions About The FormulasWhat's the difference between Caculus formulas and Differencial Calculus formulas? X'(yXβ)=0 #8 20060419 00:23:00
Re: Discussions About The FormulasDifferencial Calculus has equations that involve to different derivatives of y such as: "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..." #9 20060419 11:05:20
Re: Discussions About The FormulasSo do you mean Differential Calculus consists of Differential Equations and Partial Differential Equations? X'(yXβ)=0 #10 20060419 15:07:50
Re: Discussions About The FormulasThat would be my guess, yes. "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..." #11 20060507 15:54:02
Re: Discussions About The FormulasShould set theory contain on that which would be given in an introduction to sets? Or should it also contain things about the real numbers? "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..." #12 20060507 19:38:53
Re: Discussions About The FormulasBut that won't be too much help. X'(yXβ)=0 #13 20060508 00:21:59
Re: Discussions About The FormulasYea, I guess so. There aren't any real formulas in real analysis, only definitions and theorms. Which brings me to my next point. Formulas are computational things. That's only half of math. How about theoretical? Could we have a theory section where there would be things like definitions and theorms as well as a formula section? "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..." #14 20060508 15:01:55
Re: Discussions About The FormulasI totally agree with your idea. Sometimes it's really difficult to apply math by just referring to a formula (Or else everybody could escape from math lessons through keeping a handbook). Yet introducing the whole system would be like authoring a new book and unrealistic. X'(yXβ)=0 #15 20060508 16:45:03
Re: Discussions About The FormulasThe Formulas are developing into a really wonderful resource, but don't seem to be the right place to talk theory. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #16 20060508 22:35:31
Re: Discussions About The FormulasThe formula section is to be used as a reference, not a teaching manual. For example, d/dx sin(x) = cos(x) makes no sense unless you already understand derivatives. That's the sense I was talking about formula. Start making another reference manual. So if you want to look up the what it means to be a Cauchy sequence or the definition of an injective mapping, that would be the place. "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..." #17 20060509 09:43:30
Re: Discussions About The FormulasBut wouldn't it be nice if it were also educational? With a few extra sentences and some illustrations or whatever we could clear away the cobwebs of confusion for lots of people! "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #18 20060509 17:39:40
Re: Discussions About The FormulasWARNING: I am going to be doing some "behind the scenes" restructuring of the latex images, which may result in some "down time". "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #19 20060806 14:12:38
Re: Discussions About The FormulasI've started submitting some equations to this section, but I am beginning to have trouble. To be specific, the vector formula thread is not allowing me to post (or even preview my post, which is strange because it let me do that until recently). I get a 403 Forbidden error. Is there any explanation for this? Last edited by Zhylliolom (20060806 14:54:44) #20 20060806 16:00:40
Re: Discussions About The FormulasI can use the word curl "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #21 20060806 16:05:17
Re: Discussions About The FormulasThat's very odd. I can do it now too. Anyway, would it be alright for me to make new topics as needed on this forum? Right now I'm wanting to make a topic on inequalities. #22 20060806 16:09:33
Re: Discussions About The FormulasThat is weird, then! Maybe something to do with your browser, its cache or something. Let me know if you have other problems like it. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #23 20060806 16:14:52
Re: Discussions About The FormulasYeah, I noticed the amount of views and was pretty impressed. I'll post some differential equation stuff in the "Differential Calculus" thread for now, I guess. About people agreeing on the splitting of that thread, I vote for it, because I view differential calculus as the part of calculus I where you learn how to take derivatives of functions and apply them to other problems. Differential equations are something you do further down the line, and it might confuse someone just looking for a formula for a derivative when they run into things like integrating factors and hypergeometric functions. #24 20060807 00:14:54
Re: Discussions About The FormulasI am going to start moderating this section more heavily, so post whatever you think is right, and I'll clear up any leftover things (like the diff eq posts in the differential calc section). "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..." #25 20070205 15:34:46
Re: Discussions About The FormulasAny progress, Ricky? Character is who you are when no one is looking.
