Read the following writeup carefully: In argand plane |z| represent the distance of a point z from the origin. In general |z_1-z_2| represent the distance between two points z_1 and z_2. Also for a general moving point z in argand plane, if arg(z) =theta, then z=|z|e^(itheta), where e^(itheta) = cos theta + isintheta. Now answer the following question The equation |z-z_1|+|z-z_2|=10 if z_1 =3 + 4i and z_2 =-3 -4i represents
