**Problem 12:**

(a) Find \( y' \) if \( \tan^{-1} \frac{y}{x} = \frac{1}{2} \ln(x^2 + y^2) \).

(b) \( y = x\sqrt{x} \).

---

**Explanation for Educational Context:**

This problem requires you to find the derivative \( y' \) for two different equations. 

- **Part (a)** involves implicit differentiation of the equation involving inverse tangent \(\tan^{-1}\) and logarithmic functions.
  
- **Part (b)** involves finding the derivative of a function \( y = x\sqrt{x} \), which simplifies to \( y = x^{3/2} \). You will need to apply power rule differentiation to solve this part.
