Re: Wronskian use identities !I do not know why it should be non zero. 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. #54 20131213 05:54:48
Re: Wronskian use identities !How do you know the two solutions are linearly independent? 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. #56 20131213 07:13:08
Re: Wronskian use identities !That is true but have you used the solutions to compute the wronskian? 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. #57 20131213 07:37:03
Re: Wronskian use identities !
Can't I just write that the Wronskian is equal to: Last edited by evinda (20131213 07:37:26) #58 20131213 09:52:48
Re: Wronskian use identities !Of course you do, but you already got the solution to DE earlier. In mathematics, you don't understand things. You just get used to them.

Re: Wronskian use identities !That is what I am saying. If there is only one solution. Is there another solution? 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. #62 20131214 10:20:41
Re: Wronskian use identities !What is the other solution? 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. #63 20131214 10:26:53
Re: Wronskian use identities !There are infinitely many solutions. 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 #64 20131214 10:29:15
Re: Wronskian use identities !Yes but when you plug them into that determinant they are going to become 0. In mathematics, you don't understand things. You just get used to them.
