Question
**Topic: Application of Green's Theorem**

Suppose \(\mathbf{F}(x, y) = (4x - 3y)\mathbf{i} + 2x\mathbf{j}\)

and \(C\) is the counter-clockwise oriented sector of a circle centered at the origin with radius 2 and central angle \(\pi/6\). Use Green's theorem to calculate the circulation of \(\mathbf{F}\) around \(C\).

Circulation = \(\square\)

**Diagram Explanation:**

The diagram on the right is a vector field graph that represents the vector function \(\mathbf{F}(x, y)\). The graph displays blue arrows indicating the direction and magnitude of the vector field across the coordinate plane.

A red sector is highlighted, indicating the path \(C\), which starts from the positive x-axis and extends counter-clockwise to \(\pi/6\) radians, forming a sector of a circle with radius 2.

The coordinate axes are labeled, with integer grid lines shown, and provide a sense of scale for the graph.

(This exercise involves using Green's theorem to find the circulation of the vector field \(\mathbf{F}\) around the specified sector \(C\).)
