Integration by SubstitutionJust drafted Integration by Substitution "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20130122 07:56:14
Re: Integration by SubstitutionNo errors. 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 #3 20130122 08:29:31

Thanks!

Re: Integration by SubstitutionHi MIF; 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. #5 20130122 09:37:20

That would imply you have only two brain cells!

Re: Integration by SubstitutionThat's right, Stefy. Usually they take it in turns to run things, but, for hard questions I use them both. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #9 20130122 22:05:30
Re: Integration by Substitutionhi MathsIsFun, substitute x = sin (u) => dx/du = cos (u) substitute x = tan(u) => dx/du = sec^2(x) Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #10 20130123 07:37:40
