Re: The second imaginary number
[ QUOTE ]
[ QUOTE ] [ QUOTE ] How important is the second natural number in mathematics? I am of course talking about the number whose square is 4. [/ QUOTE ] Not very important as it is just -(h^2). [/ QUOTE ] -2(h^2) actually. [/ QUOTE ] That would be an i in your equation, not an h. |

Re: The second imaginary number
I would guess that, if you asked a mathematician to name "the second imaginary number," he would say "j" (for generalizing the complex numbers to the quaternions, just as i generalizes the reals to the complex numbers.)
But whichever definition you use, it'll be considerably less important-sounding than the first. |
