### Linear Algebra Problem Set

Consider the following vectors in \(\mathbb{R}^3\):

\[
\mathbf{u} = \begin{bmatrix} 1 \\ 0 \\ 1 \end{bmatrix}, \quad \mathbf{v} = \begin{bmatrix} 0 \\ 1 \\ 1 \end{bmatrix}, \quad \mathbf{w} = \begin{bmatrix} 1 \\ 1 \\ 0 \end{bmatrix}, \quad \text{and} \quad \mathbf{x} = \begin{bmatrix} a \\ b \\ c \end{bmatrix}.
\]

#### Tasks

(a) Are vectors \(\mathbf{u}\), \(\mathbf{v}\), and \(\mathbf{w}\) linearly independent?

(b) Do \(\mathbf{u}\), \(\mathbf{v}\), and \(\mathbf{w}\) span the entire \(\mathbb{R}^3\)?

(c) Do \(\mathbf{u}\), \(\mathbf{v}\), and \(\mathbf{w}\) form a basis of \(\mathbb{R}^3\)?

---

In this exercise, explore the concepts of linear independence, spanning sets, and basis in the context of vector spaces.
