Homework Statement
Please evaluate the line integral \oint dr\cdot\vec{v}, where \vec{v} = (y, 0, 0) along the curve C that is a square in the xy-plane of side length a center at \vec{r} = 0
a) by direct integration
b) by Stokes' theorem
Homework Equations
Stokes' theorem: \oint V \cdot dr = ∫∫ (∇ x V)\cdotn d\sigma
The Attempt at a Solution
I know I have to split up the sides of the square. I get confused when \vec{r} is involved. I know the limits are at a/2.. not sure where to go after that.
