1. Homework Statement [/b]
[itex]\int _{C} Re z^{2} dz[/itex] clock wise around the boundary of a square that has vertices of 0, i, 1+i, 1.
[itex]\int_{c} f(z) dz = \int \stackrel{b}{ _{a}} f[z(t)] \stackrel{\cdot}{z(t)}dt[/itex]
Since it is piece-wise continuous I know I need to integrate by the use of the path. So I first need to represent the path in form z(t) from a≤t≤b, find that derivative, and then sub in the values and integrate over it.
But I'm having a really hard time representing the path C in the form of z(t) (a≤t≤b), I was looking at examples but still don't get how to do it. I feel like I need to assume Re z = x and do something to get it in terms of t
Can anyone explain the steps in general any help will be very much appreciated!
