Solve the system of equations Re(z2) = 0, |z| = 2.

Given:


Re(z2)=0 and |z|=2


Let us assume Z=x+iy


Re(z2)=0


Re((x+iy)2)=0


Re(x2+(iy)2+2(x)(iy))=0


Re(x2+i2y2+i(2xy))=0


We know that i2=-1


Re(x2-y2+i(2xy))=0


x2-y2=0----------------------(1)


|z|=2



(x2+y2)=22


(x2+y2)=4-------------------(2)


Solving (1) and (2) we get


x= and y=.
