Matrices
An A × B matrix has A has A rows and B and B columns
The determinant of the 2 × 2 matrix
a b c d
The determinant of the 3 × 3 matrix
a b c d e f g h i
o
is ad – – bc
is aei + bfg bfg + + cdh – bdi – afh – ceg
If you take the first two columns of the matrix and recopy them to the right of the original matrix, the parts of the formula form diagonal lines of three elements, with the positive parts going from the upper left to t he bottom right, and the negative parts going from the upper right right down to the bottom left
You can only multiply matrices if the first first matrix has the same number o f columns as the second matrix has rows When you multiply an A an A × B matrix by a B a B × C C matrix, matrix, you get an A an A × C C matrix matrix
When you are shown simultaneous equations, t he coefficient matrix refers to the matrix formed by the coefficients of the variables (which are on the left side of the equals eq uals signs)
