### Linear Algebra Vector Operations In this section, we explore some fundamental operations involving vectors. Let’s consider the following vectors for our examples: \[ \mathbf{u} = \begin{bmatrix} -1 \\ 2 \end{bmatrix} , \quad \mathbf{v} = \begin{bmatrix} 2 \\ 3 \end{bmatrix} , \quad \mathbf{w} = \begin{bmatrix} 3 \\ -1 \\ -5 \end{bmatrix} , \quad \mathbf{x} = \begin{bmatrix} 6 \\ -2 \\ 3 \end{bmatrix} \] We will examine and compute the following operations: 1. **Dot Product Operations**: - \( \mathbf{u} \cdot \mathbf{u} \) - \( \mathbf{v} \cdot \mathbf{u} \) - \( \frac{\mathbf{v} \cdot \mathbf{u}}{\mathbf{u} \cdot \mathbf{u}} \) 2. **Dot Product with Different Vectors**: - \( \mathbf{w} \cdot \mathbf{w} \) - \( \mathbf{x} \cdot \mathbf{w} \) - \( \frac{\mathbf{x} \cdot \mathbf{w}}{\mathbf{w} \cdot \mathbf{w}} \) 3. **Scalar Multiplications**: - \( \frac{1}{\mathbf{w} \cdot \mathbf{w}} \mathbf{w} \) 4. **Projection of \( \mathbf{u} \) onto Itself**: - \( \frac{1}{\mathbf{u} \cdot \mathbf{u}} \mathbf{u} \) 5. **Projection of \( \mathbf{u} \) onto \( \mathbf{v} \)**: - \( \left( \frac{\mathbf{u} \cdot \mathbf{v}}{\mathbf{v} \cdot \mathbf{v}} \right) \mathbf{v} \) ### Detailed Explanations - **Dot Product**: The dot product of two vectors \( \mathbf{a} \) and \( \mathbf{b} \) is given by \( \mathbf{a} \cd
