Math Help - Complex numbers: how do I show unique solution?

Hi, I would really appreciate some help on part a, i'm simply getting no where. This is classed as a geometry question, but I haven't covered anything close to this in lectures yet so i'm a little confused, thanks in advance!


Moderator edit: From past Oxford moderation paper.

Hi


Conjugating :


Now try to eliminate through a combination of the 2 equations

Nice! part a is now sorted, thanks

Any chance you could give me a hint for the part about a reflection in b, all is going smoothly up to there now

This looks like part of an assignment that counts towards your final grade. Thread closed (see rule #6).
