cheers :)
Er..I think u miss out the maximum pt which is real(w)=3/2 and vertical tangent too ^^
Btw,any1 having 1902 at 8 tomoro? :)

yeah, i thought that the maximum will have a negative x coordinate...hmmm...so i just change that to positive right?? and also - what do u mean abt. vertical tangent? :confused:

yeah, i've also got 1902 lecture at 8 2moro. :)

MyLuv - you just need to sketch it.

Freaking_out - your sketch is the correct shape, but you have shown the max somewhere in Re(w) < 0, when it should be in the region Re(w) > 0.

How do I know? Well, the point z = (3 + i * sqrt(3)) / 2 lies on the circle, so w = z<sup>2</sup> = (3 + 3i * sqrt(3)) / 2 should be on your sketch. This point has Re(w) = 1.5 and Im(w) = 3 *sqrt(3) / 2 = 2.598..., clearly above (on the imaginary axis) the intercept at w = 2i.

So, your curve should be increasing as it crosses the imaginary axis, rather than decreasing. Otherwise, it looks OK.

I haven't actually figured out where the max is, so MyLuv may be right about its position, in which case the point I just chose at random happens to be the max - what a coincidence! :)

No, he's talking about the one for Re(w) < 0

You have shown it is present - if you want to go further, you'd need to find where it is...
