Having some difficulty with finding the four complex roots to the equation
Z^4 + 2i*Z^2 + 1
Not that simple, but thanks.
I have broken it into two quadratics, but as its complex I need to represent the alternative roots in terms of complex exponentials.
I am having some trouble on this stage as I think i should square root something twice, whereas my answers tells me I don't need to
thanks again for trying
