How is 1 + 1 = 1?
The definition of an antisymmetric spin means that they are in different energy states.
S+1/S -- isn't this the ratio of symmetric to antisymm spins? How would you even begin to prove this?
Yes M is an angular momentum operator. I also know that the components Mx and My do not commute. However, I do not understand how to show the greatest accuracy.
Are you saying that Mx and My are orthogonal since they do not commute?
