Express the matrix `A=[3-4 1-1]` as the sum of a symmetric and a skew-symmetric matrix.

Explanation

To express the matrix \( A = \begin{bmatrix} 3 & -4 \\ 1 & -1 \end{bmatrix} \) as the sum of a symmetric and a skew-symmetric matrix, we will follow these steps:

### Step 1: Find the transpose of matrix \( A \)

The transpose of a matrix is obtained by swapping its rows and columns. For the matrix \( A \):

\[
A^T = \begin{bmatrix} 3 & -4 \\ 1 & -1 \end{bmatrix}^T = \begin{bmatrix} 3 & 1 \\ -4 & -1 \end{bmatrix}
