| Sep 20, 2021 at 2:40 | comment | added | DanDan面 | I'm using $i$ simply for enumeration. Here, $i$ represents any integer. | |
| Sep 20, 2021 at 2:38 | comment | added | Sirou Ewei | Could you explain how the last part with imaginary number comes in? If $sin(\omega_{1}t) = sin(\omega_{2}t)$, then by trig identity, wouldn't that require $\omega_{1}=\omega_{2}$ to be true? | |
