(a) Find the eigenvalues and eigenspinors of S_y.
(b) If you measured S_y on a particle in the general state χ (Equation 4.139), what values might you get, and what is the probability of each? Check that the probabilities add up to 1.
(c) If you measured S²_y, what values might you get, and with what probabilities?
