Chapter 6: Q11P (page 314)

Evaluate each of the following integrals in the easiest way you can.
$\int_{C} (x s i n x - y) d x + (x - y^{2}) d y$ ,where Cis the triangle in the (x, y) plane with
vertices (0,0), (1,1), and (2,0).

Short Answer

Expert verified

The solution to this problem is $I = 2$

Step by step solution

Given Information

The given information is $\int_{C} (x \sin x - y) d x + (x - y^{2}) d y .$

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.

$P = x \sin x - y Q = x - y^{2}$

Find the difference of their differentiation

$\begin{array}{rcl} \frac{\partial Q}{\partial x} - \frac{\partial P}{\partial y} & = & 1 + 1 \\ = & 2 \end{array}$

The integral is in the form mentioned below.

$\begin{array}{rcl} I & = & \iint d y d x \\ = & 2 \times a r e a o f t h e t r i a n g l e \\ = & 2 \end{array}$

Hence, the solution to this problem is . $I = 2$
