Proof of 2D rotation commutativity

In summary, to prove that 2-dimensional rotations (via matrix transformations) are commutative, one can substitute trigonometric variables in two matrices and calculate them in different orders to show that the resulting matrices are the same. This is a sufficient proof.

The Attempt at a Solution



I believe subbing in trig variables in two matrices and then calculating them in different orders would result in the same matrix and prove it, but I am not sure it is sufficient.
