1. Hey I saw that question about the image you were talking about.

Because it's a circle, it's a hint to use polar coordinates. So you can write z = 2cis(theta) and then
f(z) = 2cis(theta) - 0.5cis(-theta)
= 2(cos(theta) + isin(theta)) - (0.5cos(theta) - 0.5isin(theta))
= 1.5cos(theta) + 2.5isin(theta)

So x = 3cos(theta)/2 and y = 5sin(theta)/2 and you can see it's an ellipse.

Sorry, thought I'd better tell you because I led you off before!
