... Note that since rotations preserve orientation, while reflections reverse it, these two possibilities are mutually exclusive. We will call transformations which preserve orientation sense preserving, while those that do not preserve orientation will be called sense reversing. Use the following Lemma ...

... for the non-evident definition of matrix multiplication. Component-wise multiplication of matrix entries turns out to be almost completely useless in applications. Now, the bad news. Matrix multiplication is not commutative — that is, BA is not necessarily equal to A B. For example, BA may not be de ...
