Question
### Chapter 14 Problems:

**Problem 11:**

Consider the function \( f(x, y) = x^2y e^{-x^2-y^2} \). Compute \(\nabla f\) and the directional derivative \( D_{\mathbf{u}} f \) where \(\mathbf{u} = (1, 2)\).

**Explanation:**

- **Function \( f(x, y) \):** This is a multivariable function involving exponential decay with respect to both \( x \) and \( y \).
  
- **Gradient \(\nabla f\):** This is the vector of partial derivatives of the function, representing the direction of the steepest increase of \( f \).

- **Directional Derivative \( D_{\mathbf{u}} f \):** This measures the rate of change of the function \( f \) in the direction of \( \mathbf{u} \). Given \(\mathbf{u} = (1, 2)\), this vector denotes the specified direction in which the derivative is computed.
