Question
![**Problem 3: Application of the Chain Rule in Partial Differentiation**
Use the chain rule to find the partial derivatives \(\frac{\partial z}{\partial u}\) and \(\frac{\partial z}{\partial v}\) for the function:
\[
z = \cos x \sin y
\]
Given the transformations:
\[
x = u - v, \quad y = u^2 + v^2
\]
**Instructions:**
- Use the chain rule method.
- Do not substitute the expressions for \(x\) and \(y\) into \(z\) before differentiating.
- Write your final answers as functions of only \(u\) and \(v\).
**Note:** This problem requires understanding of the chain rule in multivariable calculus to express the dependencies and find the respective derivatives.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7979a14f-8975-4e35-993d-177e61b75e93%2F851b9078-5a61-4a3e-9dec-b5ecda05dba0%2Fz0lys3b_processed.png&w=3840&q=75)
