## Homework Statement

Let C be a contour formed by the points O(0,0), A(1,0), B(1,1), with the direction OA->AB->BO. By using the definition of a contour integral, evaluate:

(integral) f(z)dz

## Homework Equations

[tex]\int f[z(t)]z'(t)dt[/tex]

## The Attempt at a Solution

I didn't include the work I've done, or even the function upon which I am integrating. I'm looking more for an understanding.

I perform the line integrals about each side of the triangle, and sum each value at the end. But I end up with 0, which I think makes sense since this is a closed region. But should the value equal zero?
