Chapter 14: Q 6 (page 1153)

Determine whether the vector fields that follow are conservative. If the field is conservative, find a potential function for it.
$F (x, y) = <(1 + x y) e^{x y}, e^{x y}>$

Short Answer

Expert verified

The vector field is non conservative

Step by step solution

Step 1:Given information

The given expression is $F (x, y) = <(1 + x y) e^{x y}, e^{x y}>$

Step 2:Simplification

Consider the vector field,

$F (x, y) = <(1 + x y) e^{x y}, e^{x y}>$

A vector field $F (x, y) = P (x, y) i + Q (x, y) j$ is conservative if and only if

$\frac{\partial P}{\partial y} = \frac{\partial Q}{\partial x}$

Comparing $F (x, y) = <(1 + x y) e^{y}, e^{y y}>$ with $F (x, y) = P (x, y) i + Q (x, y) j$

Then,

$P = (1 + x y) e^{x y}$

$Q = e^{x y}$

now calculating

$\frac{\partial P}{\partial y}, \frac{\partial Q}{\partial x}$

$\frac{\partial P}{\partial y} = x e^{x y} + x e^{x y} + x y e^{x y}$

and

$\frac{\partial Q}{\partial x} = y e^{x y}$

Since, $\frac{\partial P}{\partial y} \neq \frac{\partial Q}{\partial x}$

Therefore the vector field is non conservative
