Short Answer

Expert verified

The solution to this problem is /=-20.

Step by step solution

Given Information.

The given information is $\oint (2 y d x - 3 x d y)$

Definition of Green’s Theorem.

The Green's theorem connects a line integral around a simple closed curve C to a double integral over the plane region D circumscribed by C in vector calculus. Stokes' theorem has a two-dimensional special case.

Find the solution.

Write the values of P and Q.

P = 2y

Q = - 3x

Find the difference of their differentiation

$\frac{\partial Q}{\partial x} - \frac{\partial P}{\partial y} = - 3 - 2 = - 5$

The integral is in the form mentioned below.

$I = - 5 \int_{1}^{3} \int_{3}^{5} d x d y = - 5 \times 4 = - 20$

Hence, the solution to this problem is / = - 20.
