Math Complex numbers help?
I will answer one question, and I am choosing: 3) Find all complex numbers z such that |z-1|=|z+3|=|z-i|. This means z is equidistant from 1+0i, -3+0i, and 0+i. finding the intersection of the perpendicular bisector of the first two numbers, and that of the last two numbers we get: z = -1-i ⇦ ⇦ ⇦
