| Nov 22, 2010 at 16:21 | comment | added | user68 | @KennyTM Quite obvious while this is a nonlinear equation. My point was just that "linearity" of equations does not imply that the solutions are linear functions (though it implies superposition). | |
| Nov 22, 2010 at 16:14 | comment | added | kennytm | @mbq: Consider the nonlinear equation $\dot x + x^2 = 0$, both $1/t$ and $1/(t-1)$ are solutions, but the "superposition" $1/t + 1/(t-1)$ is not. | |

| Nov 22, 2010 at 16:12 | comment | added | Marek | @mbq: first of all, I wouldn't call a solution of linear equation, which is nonlinear in time, nonlinear. The solutions are almost never linear in time, so it is just plain confusing. Second, OP's question is not a real question (I voted to close) so I don't think there is any reasonable answer. Third, even if there were a good answer, yours is more like a comment about quite irrelevant piece of terminology. | |
| Nov 22, 2010 at 16:03 | comment | added | user68 | @Marek Yes, but I can't see why it is a problem. One can superpose nonlinear solutions to get a nonlinear solution. | |
| Nov 22, 2010 at 15:56 | comment | added | Marek | That's true but this is never meant by linearity of equations/theory. Linearity always has to do with superposition. | |
