... We denote the 2 × 2 multiplicative identity matrix by I2 , and as such, M · I2 = I2 · M = M for any 2 × 2 matrix M . This is one example of a situation where multiplication is commutative for 2 × 2 matrices. Do not be fooled, in general, M1 · M2 ̸= M2 · M1 , so order matters. However, we do get that ...

... (y1 , y2 , · · · , yn ) = F (x1 , x2 , · · · , xn ) and (x1 , x2 , · · · , xn ) = G(y1 , y2 , · · · , yn ) are two transformations such that (x1 , x2 , · · · , xn ) = G(F (x1 , x2 , · · · , xn )) then the Jacobian matrices DF and DG are inverse to one another. This is because, if I(x1 , x2 , · · · , ...
