comment Given the degrees to rotate around axis, how do you come up with rotation matrix?
then angle theta changes for each one of the rotation matrices, right? rotating 45 deg around x-axis and 90 deg around y-axis then the theta used in cos and sin for $R_x$, $R_y$ and $R_z$ are different, right?

Since matrix multiplication is associative I can just multiply $R_yR_x$ and multiply the resulting matrix by the vector, right?
