Diskusjon:Imaginær enhet
Fra Wikipedia, den frie encyklopedi
I understand that in the article is spoken of "the positive i". This is a meaningless expression. There is not such as a positive, nor a negative i. The equation x2 = − 1 has no real solution. We may introduce a solution and call it i. As a consequence also -i is a solution. But the solution we call i, is the imaginary unit.130.89.222.126 3. sep 2006 kl. 15:55 (UTC)
- «Men dette løser seg ved at vi velger alltid å bruke den positive i som løsning.» – But this isn't a problem as we choose to always use the positive i as a solution. — Jeblad 3. sep 2006 kl. 17:42 (UTC)
