Question
**Problem Statement** Determine whether the following statement is true or false: If \( A = \begin{pmatrix} 0 & 1 \\ -1 & 0 \end{pmatrix} \), then the eigenvalues of \( A^2 \) are non-negative. Provide an explanation for your answer. **Explanation** - **Matrix \( A \)**: A 2x2 matrix is given as \( A = \begin{pmatrix} 0 & 1 \\ -1 & 0 \end{pmatrix} \). - **Eigenvalues of \( A \)**: Calculate the eigenvalues of matrix \( A \) to inform further calculations. - **Square of Matrix \( A \) (\( A^2 \))**: Determine \( A^2 \) by multiplying matrix \( A \) by itself. - **Eigenvalues of \( A^2 \)**: Evaluate the eigenvalues of the resulting matrix \( A^2 \) to determine if they are non-negative. - **Conclusion**: Analyze the eigenvalues to verify the truthfulness of the statement.
