Step-by-step explanation:
The objective is to find the line integral of around the perimeter of the rectangle with corners (4,0), (4,3), (−3,3), (−3,0), traversed in that order.
We will use <em>the Green's Theorem </em>to evaluate this integral. The rectangle is presented below.
We have that
Therefore,
Let's calculate the needed partial derivatives.
Thus,
Now, by the Green's theorem, we have
