Sketch the following
i) the set of all z such that Arg(z) = -3Pi/4
ii) the set of all z such that z=8e^itheta and 5Pi/4 less than or equal to theta less than or equal to 3Pi/2
For i) Would this just be lines 135o from x axis and repeat 360o .

Yes to i)
ii) Draw the half-lines at the appropriate angles ( 195° and 270°) and draw an arc of a circle radius 8 (from 8eiθ ) centre (0,0) between the two half-lines.
