Thank you

Thanks Prof, but I don't understand how u find x' and y'?

You didn't mention the determinant (=+1) so the length(norm) of vector remains unchanged, an important requirement for a rotation matrix. Obvious but still, simple test for to see if some matrix in R^n could be a rotation matrix.

Great video... I keep getting distracted with wondering if he has to write backwards to make the text look correct to us?

Another way of thinking about this is this is a rotation through the Z axis. And the 3D rotation matrix for the Z axis is the same in what he found for R_theta!
