Hi
I need some help on this complex number question.
Find the four roots of the equation z^4 = -1.
answer in form of a + jb where a and b are real.
Thanks
this one is quite simple to solve, it is simply a quadratic in terms of z²
by the s and t subscripts, i mean that you can have them in any combination, one is not dependant on the other, in otherwords:

That's interesting, I've never seen that notation before. Do the s and t mean anything or are they just arbitrary distinguishing symbols?
Why did the vector cross the road?
It wanted to be normal.

Thanks for your reply.
how did u get

they don't mean anything, its just to distinguish that they are not related, im not sure if its a proper notation, but ive seen it used before, and i often use it in this case.
for the 1/√2 i got that from typing it into google im not sure how you work it out, i havn't covered complex numbers yet in my studies, im guessing its one of those things you're just meant to learn, the same way you learn sin30° = 0.5, or sin45° = 1/sqrt(2) etc
