Fuck off and euthanize yourself you dirty fucking frogshitter.

>>8452930
Yes, but that is not the reason

Euthanize yourself, brainlet. With this attitude you won't solve any problem and you won't be allowed into any competent place.

You're also probably a talentless faggot, I have seen enough retards like you to know.

In quaterion algebra you get i, j && k.
i*j=k, j*k=i k*i=j j*i=-k k*j=-i i*k=-j ijk=i^2=j^2=k^2=-1

it's just notation, as long as it's defined clearly and doesn't create confusion i'm ok with everything

[eqn]e^{j\tau}=-j^2[/eqn]

this guy gets it.

moreover, all of complex analysis and DEs holds if you work in the Real-j pane instead of the Real-i pane.

by choosing a different quaternionic subset, electrical engineers and physicists get the benefit of continuing the i(t) current tone variant function notation.

looks like OP doesn't understand math OR it's applications. what a shame.

Why is it, then?

Okay, but i, j, and k are still arbitrary variables. They could just as easily be k, i, and j. Or they could be wall, London, and nigger.

You can call variables whatever the fuck you want, so why are you guys arguing?

>>8453241
the purpose is standardization of notation without entirely divorcing from mathematics. don't think there is much of an argument, OP just seemed angry and confused

>Should we euthanize engineers?
unlike mathcucks we deal with reality. and in reality you have moving charges. and moving charges are called what?! YES A CURRENT.
honey and which symbol is usually used for current?

YES NOW FUCK OFF

>>8453144
Are those not supposed to be wedge products? Or am I that rusty in my algebra?
