Question

Describe fully the locus of the points representing z if (z+2i)/(z-2i) is purely imaginary

Answer 1

The radius of the circle is 4 so a²+b²=4²

Explanation:

Answer 2

♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫

➷ The locus would be a circle with the radius 2

you can write it as a^2 + b^2 = 4^2

(the results value represents the locus of points for z)
