Re: πI'm done with the painting and the surprise I got was that I realised that I do not paint so well like my classmates. '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?'

Re: πHi;
I do not know that one. 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. #28 20130811 01:16:33
Re: πI think it is better known as Devi Mahatmya 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: πI doubt it. Probably read about it on my own. 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. #32 20130811 02:56:03
Re: πOk, what should I be computing? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: πCompute say 100 terms of that series and tell me what you get. 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.

Re: πYes, although there is a big = sign there the series is useless for computation. We would need many millions of terms for 5 or 6 digits of accuracy. 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. #36 20130811 03:27:57
Re: πWow. That is pretty impressive. '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 #38 20130811 03:34:52
Re: πSurely, I do! '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 #39 20130811 03:35:14
Re: πOkay, let me find 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. #41 20130811 13:20:47
Re: πYes, believe it or not that converges to pi and was one of the earliest used to get lots of digits. 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. #42 20130811 13:50:47
Re: πBut that does not look like any infinite series. How can you use the term 'converge'? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun.

Re: πDo you remember the Taylor series for arctan(x)? 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. #44 20130811 14:10:44
Re: πSo, thats the same thing written in a different way? '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 #45 20130811 14:13:23
Re: πYes, but we have two series to sum instead of one. With n = 10 we get 3.1415926535897932947 which has 17 correct digits! 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. #46 20130811 15:01:46
Re: πCode:>>> 16*atan(1.0/5.0)  4 *atan(1.0/239.0) 3.1415926535897936 I am supposed to get 3.1415926535897932 '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 #47 20130811 15:03:41
Re: πYou were probably a victim of subtractive cancellation. We have not covered that yet. We are back in the world of computation and much mathematics does not hold or has to be modified. 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. #48 20130811 15:15:22
Re: πThat is what has been done in post 46. Don't you think? '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 #49 20130811 15:19:54
Re: πIn post #46 you plugged in to a formula. Unfortunately in computation summing the series and plugging in are two very different algorithms. In math you of course expect the same answer. In computation you do 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. #50 20130812 00:59:52
Re: πok, I will do it '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
