How could I use Mathematica to give me a plot of the locus of z such that
[tex]\arg(\frac{z-2}{z+5}) = \frac{\pi}{4}[/tex] ?
I've tried using ContourPlot and typing
ContourPlot[Arg[(x - 2 + I)/((x + 5) + I)] == (\[Pi]/4), {x, -5, 5}, {y, -5, 5}]
but it just gives me two vertical lines. I think the correct graph should be the arc of a circle passing through (-5,0) and (2,0).
Many thanks!
