![**3. Evaluate**
\[
\int_a^b \int_c^d \frac{xy^2}{x^2 + 1} \, dy \, dx.
\]
By splitting into the product of two single integrals. When can you split an integral like this?
**Explanation:**
This mathematical expression is a double integral, which suggests finding the volume under the surface defined by the function \( \frac{xy^2}{x^2 + 1} \) over the domain defined by the intervals \([a, b]\) for \(x\) and \([c, d]\) for \(y\).
To evaluate this by splitting into the product of two single integrals, check if the integrand \( \frac{xy^2}{x^2 + 1} \) can be separated into a product of a function solely in terms of \(x\) and a function solely in terms of \(y\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F763773a4-b59e-428b-8a3f-bc3dd5fb97d6%2Fc39de336-5686-42f5-a466-051eda51d46e%2F121dkkc_processed.png&w=3840&q=75)
