Re: An Integral and the ComputerThat is okay '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 #102 20130726 00:49:57
Re: An Integral and the ComputerEarly night. I will begin preparing what I know about 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. #103 20130726 01:01:05
Re: An Integral and the ComputerWhats your time now? '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 #104 20130726 01:02:07
Re: An Integral and the Computer8:00 am and soon I will be going offline. 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. #105 20130726 01:19:29
Re: An Integral and the ComputerOK Have a good day '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 #106 20130726 01:20:48
Re: An Integral and the ComputerHere is the difference in the two methods. 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. #107 20130726 03:10:42
Re: An Integral and the ComputerImpressive... '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 #108 20130726 14:04:42
Re: An Integral and the ComputerAre you sure it starts with h/3? '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 #109 20130726 14:05:03
Re: An Integral and the ComputerSorry, we were both posting at the same time and I could not edit fast enough. with h = (ba)/n x_i = a + i*h 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. #110 20130726 22:43:16
Re: An Integral and the Computer'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: An Integral and the ComputerIt's convergence is much faster than the trapezoidal rule. 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. #112 20130726 23:18:09
Re: An Integral and the ComputerSo, should I program 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 #113 20130726 23:19:00
Re: An Integral and the ComputerIf you like, then we will see if our answers compare. 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. #114 20130726 23:36:33
Re: An Integral and the ComputerCode:def integrate(f, a, b, n): h = float(ba)/n x = lambda i: (a + i*h) s1 = 0 for j in xrange(1,(n/2)): s1 += f(x(2*j)) s1 *= 2 s2 = 0 for j in xrange(1,(n/2)+1): s2 += f(x(2*j  1)) s2 *= 4 s = h/3*(f(x(0)) + f(x(n)) + s1 + s2) return s 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: An Integral and the ComputerLet's try it on your integral with n =30. 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. #116 20130727 02:07:56
Re: An Integral and the ComputerI am getting that too. '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 #117 20130727 02:10:49
Re: An Integral and the ComputerI could make a drawing for you later that might help. 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. #118 20130727 02:14:21
Re: An Integral and the ComputerThat I can do for myself with a lot more colors than you would use xD '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 #119 20130727 02:20:19
Re: An Integral and the ComputerYou have a nice program that you can use later on to integrate functions that you will not be able to do by hand and there will ne lots of them. 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. #120 20130727 02:24:25
Re: An Integral and the ComputerWhy will integration problems come to me in the reality? '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 #121 20130727 02:26:27
Re: An Integral and the ComputerIntegration is the area under a curve. They come up in physics and probability a lot. 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. #122 20130727 02:29:22
Re: An Integral and the Computerhahaha '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 #123 20130727 02:30:15
Re: An Integral and the ComputerI figured you wanted a real formula and not a bobbym creation. 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. #124 20130727 02:34:33
Re: An Integral and the ComputerNope. I want something that gives me the geometric feeling of the area. It can be anything, a program or a formula or some philosophy. '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 #125 20130727 02:35:56
Re: An Integral and the ComputerI looked at two geogebra programs but they were not very impressive. 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.
