| Apr 6, 2013 at 12:44 | comment | added | 71GA | I would appreciate if you could show me how to transform $C \sin(\mathcal L x) + D \cos (\mathcal L x)$ using euler formula. Afterall i don't have $i\sin()$. | |
| Apr 6, 2013 at 11:03 | comment | added | Michael | Why do you think $\mathrm{e}^{-i\mathcal{L}x}$ would go to infinity? $\mathrm{e}^{i\theta}$ has constant magnitude $=1$ for all real $\theta$. The complex exponentials are just a way of rewriting the solution in terms of $\cos$ and $\sin$. In your second form the minus sign should go under the square root -- $\mathcal{L}$ is imaginary in that case. | |

It seems the homework tag applies even if it is not actual homework
