I just need a confirmation on the question (picture): Do I just make so that that matrix times its transpose equal to 1 and solve it?

You need to check the two products, because the matrix product, in general, does not obey the commutation rule of the product. \[Q^TQ=QQ^T=I\] The two first products must be satisfied.

Yes, but this time you'll have no problem. The two products give the same results. ;)

Ok just to confirm that I got it right, does alpha have to be either positive or negative 1/2 or 0?
