(a) look at these the complex numbers z1 = − √ 3 + i and z2 = 3cis(π/4). write the following complex numbers in polar form, writing your answers in principal argument:
i. z1
ii. z1/|z1|. Additionally, convert only this answer into Cartesian form.
iii. z1z2
iv. z2/z1
v. (z1) -3
vi. All complex numbers w that satisfy w 3 = z1.
(b) On an Argand diagram, sketch the subset S of the complex plane defined by S = {z ∈ C : |z − i| ≤ 1, |z + 2 − 3i| ≤ |z − 2 + i|}.
