**1) How do you integrate 1/ [z^2] over the unit circle?**

After you integrate, do you put it in polar form or do you replace z with x + iy then solve it?

I keep getting zero. It should exist since z=o is undefined, right?

**2) How do you integrate x dz over gamma, when gamma is the straight line path from 0 to 1+i?**

I have looked at some examples that put the line in

**y=mx +b**form, then integrate it w/ respect to y, but my professor gave us this equation:

**gamma(t)= (1-t)P + tQ.**I don't know where it comes from, so that's confusing me. The fact that it's the integral of x dz confuses me, too.

Thanks.
