argand diagram
. A and B are points in an Argand diagram representing the complex numbers 1 and i. P is a point on the circle having AB as a diameter. If P represents the complex number z, find the value of arg(z1/zi) if P is in (a).the first quadrant, (b).the second quadrant (c).the fourth quadrant.

The circle passes through the origin(0,0) .... Show us some of your work.....................

Re: argand diagram
if u take z=a+ib and use tan A tan B formula we can prove we are dealing with a circle but hw do we knw which quadrant to consider
