Question
![**Problem Statement:**
Find the derivative \(\frac{dy}{dx}\) given the equation:
\[
\sin(xy) = y
\]
**Solution:**
\(\frac{dy}{dx} = \) [Provide your answer here based on the calculation using implicit differentiation or other techniques as applicable.]
**Explanation of Concepts:**
1. **Implicit Differentiation:**
- Use implicit differentiation when both \(x\) and \(y\) are mixed through a trigonometric function as shown in the equation \(\sin(xy) = y\).
- Differentiate both sides of the equation with respect to \(x\), remembering to apply the chain rule for the \(\sin(xy)\) term.
2. **Chain Rule:**
- When differentiating \(\sin(xy)\), recognize that \(xy\) itself is a product of two functions. Use the chain rule to differentiate effectively.
3. **Steps:**
- Differentiate \(\sin(xy)\) using the chain rule to find \(\cos(xy) \cdot (x \cdot \frac{dy}{dx} + y)\).
- Differentiate \(y\) on the right side as \(\frac{dy}{dx}\).
- Solve for \(\frac{dy}{dx}\) by equating and simplifying the differentiated equation.
Note: This explanation should guide users through solving a differentiation problem where the typical separation of variables might not be straightforward.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd1f0f51f-f003-4ca2-9c03-b14a76478a3a%2F71740479-98f2-49d8-b7ab-aff4babc6162%2Fxktjhln_processed.jpeg&w=3840&q=75)
