Chapter 14: Q. 37 (page 1096)

Show that the vector fields in Exercises 33–40 are not conservative.
$F (x, y, z) = 2 i - z j + e^{yz} k$

Short Answer

Expert verified

The vector fields is not conservative because $\frac{\partial F_{1}}{\partial z} \neq \frac{\partial F_{2}}{\partial y}$ .

Step by step solution

Step 1. Given Information

We have to show that the vector fields in the given exercise is not conservative.
$F (x, y) = 2 i - z j + e^{yz} k$

Step 2. A vector field F(x,y)=(F1(x,y),F2(x,y)) is not conservative if and only if ∂F1∂z≠∂F2∂y.

For the vector field $F (x, y) = 2 i - z j + e^{yz} k$

$\frac{\partial F_{1}}{\partial z} = \frac{\partial}{\partial z} (- z) \frac{\partial F_{1}}{\partial z} = - 1$

Step 3. Now finding ∂F2∂y

$\frac{\partial F_{2}}{\partial y} = \frac{\partial}{\partial y} e^{y z} \frac{\partial F_{2}}{\partial y} = z e^{y z}$

Hence, $\frac{\partial F_{1}}{\partial z} \neq \frac{\partial F_{2}}{\partial y} .$
