##[a\,b]^T =aX_++bX_{-}##

My first doubt is what does this general state mean? Isn't there only two states of spin, spin up and spin down?

and to find the matrices of ##S^2## and ##S_z## he uses their eigenvector equation to find that but why is the same method not employed for finding the matrices for ##S_x## ##S_y## ? He gets their respective matrices using a sum of raising and lowering operators Also he ends up with an eigen spinor with a different value. So am pretty much confused with how they came to be.
