Dear All,(adsbygoogle = window.adsbygoogle || []).push({});

Please help me clear some doubts about Theorem 3.3.1 in the 1st attachment.

The condition ## |a| = |b| ## has only 8 cases right? ## { x+iy. x - iy, -x + iy, -x - iy, y + ix, y - ix, -y + ix, -y - ix } ##

so for the condition ## |a| = |b| ## and ## b \bar c = \bar a c ## in (2) and (3) in the attachement, what must ##b## and ##\bar a## be for them to to satisfy this equation given that C is a complex number of the form ## Cx + iCy ##.

why is there a line of solutions in (3)? usually you only get one imaginary and one real value for z right??

In the 2nd attachement, I have tried to do question 3. what does in the direction of b mean? does it pass through b also?? c =0 right? can you please give examples of the complex number b?

Danke...
