Re: Integration by SubstitutionHi anonimnystefy, "Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense"  Buddha?

Re: Integration by Substitutionwithout the solution it would be hard to understand solution!

Re: Integration by SubstitutionUntil there is a solution, there is no solution!

Re: Integration by Substitutionnot quite,the solution exists wheter you find it or not.except if there is no solution at all 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 #84 20110812 00:09:00
Re: Integration by SubstitutionIf we don't have a solution, it means it's in the closed book.

Data!" he cried impatiently. "I can't make bricks without clay." #85 20110812 00:11:15
Re: Integration by Substitutionmaybe there is no book that holds that exact solution.does the solution exist then?yes,you just have to find it.

Re: Integration by SubstitutionHi gAr; 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. #93 20120405 22:39:44

Re: Integration by SubstitutionYes,you are correct.I forgot to make a change of limits of integration when I used substitution.

Re: Integration by SubstitutionI believe these questions from the original post haven't been answered yet. I guess the only one remaining to be answered is #20
