Question
I'm currently facing challenges in solving this problem using only matrix notation, and I'm in need of your guidance. The problem specifically demands a solution using matrix notation exclusively, without any other methods. Could you kindly provide a step-by-step explanation, utilizing matrix notation, to help me grasp and solve the problem until we reach the final solution?
can you please do this step by step without skipping any steps so I can understand it better and this has to be done using the mattrices way
![### Problem Description:
2. **Find the eigenvalues and eigenvectors of the matrix \( A \)**
\[
A = \begin{bmatrix}
2 & 3 & 3 \\
-3 & -4 & -3 \\
3 & 3 & 2 \\
\end{bmatrix}
\]
If \( A \) is diagonalizable, find a matrix \( P \) and a diagonal matrix \( D \) such that \( P^{-1}AP = D \).
If \( A \) is diagonalizable, calculate \( A^9 \begin{bmatrix} 1 \\ 0 \\ 2 \end{bmatrix} \).
---
### Explanation:
- **Eigenvalues and Eigenvectors:**
To find the eigenvalues of the matrix \( A \), we solve the characteristic equation \( \det(A - \lambda I) = 0 \), where \( \lambda \) represents the eigenvalues and \( I \) is the identity matrix.
Once the eigenvalues \(\lambda\) are determined, the corresponding eigenvectors can be found by solving \( (A - \lambda I)x = 0 \) for each \(\lambda\).
- **Diagonalization:**
If the matrix \( A \) is found to be diagonalizable, this means there exists a matrix \( P \) formed by the linearly independent eigenvectors of \( A \), and a diagonal matrix \( D \) formed by the eigenvalues of \( A \) such that:
\[
P^{-1}AP = D
\]
- **Exponentiation and Transformation:**
To calculate \( A^9 \begin{bmatrix} 1 \\ 0 \\ 2 \end{bmatrix} \), the diagonalization method can be used where:
\[
A^9 = (PDP^{-1})^9 = PD^9P^{-1}
\]
Using this, we can multiply \( A^9 \) by the vector \( \begin{bmatrix} 1 \\ 0 \\ 2 \end{bmatrix} \) to obtain the required result.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F721da9e6-56ca-4fff-bad1-06b01dcc2531%2Fc4af26b9-d49d-4c33-b09d-dafdd90793bb%2Fhb73ab_processed.jpeg&w=3840&q=75)
