How to calculate the determinant of a Matrix. SARRUS RULE. What is necessary to have a determinant? The Matrix must be square (have the same number of rows and columns) (0:20) Representation of a matrix and a determinant (0:30) EXERCISE: Calculating the determinant of a square matrix of order 2 by 2 (0:35) How to calculate the determinant? Multiply the elements of the main Diagonal and the elements of the secondary Diagonal. After that, take the result of the main Diagonal and subtract it from the result of the secondary Diagonal. (0:45) EXERCISE: Calculating the determinant of a matrix of order 3 by 3 (1:45) Hint: repeat the 1st and 2nd columns, known as the SARRUS RULE Then multiply all the elements of the main diagonal and then the elements of the secondary diagonal. Finally, take the result of the main diagonal and subtract it from the result of the secondary diagonal.
