...just curious what are the different types of locus graphs and stuff like arg(z-2i/z+3)=pi/3 cause i cant find them on google, spent several hours....and how would you determine what it looks like on the argand diagram?...

you can't really find graphs on google, better to check it up in a book. On the argand diagram isnt it just a part of a circle ( or full) with the angles + radius set out differently depending on the graph o-o

Hi mate,

P will be the locus of the circle on the Argand diagram.

Think of angle in the same segment in circle geometry with the angle being pi/3...

-3 ie. (-3, 0) and 2i ie. (0, 2) will form the chord of the circle.

Cheers
Stuart

If you have Arnold 4 unit cambridge. Go to 2.5, curves and regions in the argand diagram and spend some time looking through all the examples.
