I have no idea what a locus means so The complex number u is
given by u=(7+4i)/(3-2i). In the form x+yi, x=i, y=2 Sketch and
argand diagram showing the point representing the complex number
u. Show on the same diagram the locus of the complex number z
such that [z-u]=2. Give a thorough description would be good.
Find the greatest value of argument. Urgent.
