Question

please answer the following question with the formula listed

**Question 11:**

Let's try the Gram-Schmidt process of orthogonalization with the matrix:

\[
\begin{bmatrix}
0.223 & 0.668 & 0.710 \\
-0.125 & 0.741 & 0.660 \\
0.795 & -0.234 & 0.560 \\
\end{bmatrix}
\]

What is the y-coordinate of r3-prime? (Don't normalize r3-prime, simply follow the steps, do not use the cross product)

Round your answer to 3 decimal places.

The text in the image appears to be a series of vector equations used in mathematics, possibly in the context of numerical methods or linear algebra. The equations are as follows:

1. \( \mathbf{r}_1' \gets \mathbf{r}_1 \),
2. \( \mathbf{r}_2' \gets \mathbf{r}_2 - \frac{\mathbf{r}_2 \cdot \mathbf{r}_1'}{\mathbf{r}_1' \cdot \mathbf{r}_1'} \mathbf{r}_1' \),
3. \( \mathbf{r}_3' \gets \mathbf{r}_3 - \frac{\mathbf{r}_3 \cdot \mathbf{r}_1'}{\mathbf{r}_1' \cdot \mathbf{r}_1'} \mathbf{r}_1' - \frac{\mathbf{r}_3 \cdot \mathbf{r}_2'}{\mathbf{r}_2' \cdot \mathbf{r}_2'} \mathbf{r}_2' \).

Explanation:

- These equations appear to describe a process of vector orthogonalization, possibly using the Gram-Schmidt process.
  
- \( \mathbf{r}_1' \) is initialized as \( \mathbf{r}_1 \).

- \( \mathbf{r}_2' \) is obtained by projecting \( \mathbf{r}_2 \) onto \( \mathbf{r}_1' \) and then subtracting this projection from \( \mathbf{r}_2 \), ensuring \( \mathbf{r}_2' \) is orthogonal to \( \mathbf{r}_1' \).

- \( \mathbf{r}_3' \) is computed similarly by orthogonalizing \( \mathbf{r}_3 \) with respect to both \( \mathbf{r}_1' \) and \( \mathbf{r}_2' \), ensuring it is orthogonal to both.

These steps are fundamental in creating an orthogonal set of vectors from a linearly independent set.
