**Problem 0.2**

Consider a \(2 \times 2\) matrix

\[
U = \begin{bmatrix} 1 & 1 \\ 0 & 1 \end{bmatrix}.
\]

1. Compute \(U^2\), \(U^3\), and give an explicit formula for \(U^n\).

2. Let \(L_U : \mathbb{R}^2 \rightarrow \mathbb{R}^2\) be the linear transformation given by \(L_U(\vec{x}) = U \vec{x}\). For a given unit square 

   \[
   S = \{(x, y) : 0 \leq x, y \leq 1\},
   \]

   sketch the image \(L_U(S)\) of \(S\).

3. Is \(U\) diagonalizable?
