![**Evaluating Line Integrals Over Curves**
We want to evaluate the line integral \(\oint_C \mathbf{F} \cdot d\mathbf{r}\), where:
\[
\mathbf{F}(x, y) = \langle e^{2x} + x^2y, e^{2y} - xy^2 \rangle
\]
and \(C\) is the circle defined by the equation \(x^2 + y^2 = 1\), oriented clockwise. The question is: how is this integral related to the integral over the curve oriented counter-clockwise?
**Options:**
- ☐ The two integrals are the same.
- ☐ The clockwise integral is not defined; we can only integrate in a counter-clockwise direction.
- ☑ The integral over the clockwise curve is the opposite sign of the integral over the counter-clockwise curve.
- ☐ The two integrals give completely different values.
**Explanation:**
For line integrals over closed curves, reversing the direction of the curve changes the sign of the integral. Therefore, the integral over the clockwise curve will be the negative of the integral over the counter-clockwise curve.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fef181dc2-fef5-43c0-ba63-c5f0d82b0b96%2Ff48f1128-e1bc-4b08-92b7-e8149d06eae1%2F5r6ykn_processed.jpeg&w=3840&q=75)
