Question

if modulus of z1 =mosulus of z2 is it necessary that z1= z2 ? justify answer with an example​

Answer 1

Answer:

|Z1| = |Z2| then z1 and z2 are at the same distance from origin. But if arg(Z1) ≠arg(z2), then z1 and z2 are different. So, if (z1| = |z2|, then it is not necessary that z1 = z2.
