1.2.21 Determinant calculation
condition: Calculate the fourth-order determinant using the row or column expansion method. \[ \left|\begin{array}{cccc} 1 & 1 & 0 & 2 \\ 2 & -2 & 0 & -1 \\ -1 & 2 & 2 & -1 \\ 0 & 1 & 0 & 1 \end{array}\right| \]
Calculation of determinants - both simple and complex, both low orders and higher ones.
