| Mar 11, 2015 at 22:48 | comment | added | Simon B. | @FedorPetrov that's the point here. I took the wronskian set it equal to zero and substituted the derivatives. | |
| Mar 11, 2015 at 22:39 | comment | added | Fedor Petrov | @YemonChoi it may happen if we arrive to equation assuming something which must be wrong:) | |
| Mar 11, 2015 at 21:50 | comment | added | Yemon Choi | I still don't understand. Normally when someone says they arrive at an equation, that means they have derived it from something and they think it is true. So why did you write down this formula and ask for help proving it is false? | |

| Mar 11, 2015 at 19:13 | comment | added | Yemon Choi | I am confused: you've written down an equation, and then you say "I want to show that we have don't have equality unless $x\in\{-1,1\}$". | |
