We may say that when the state-vector is + or - respectively, sz is equal to /2 and - /2 respectively, but, if one restricts oneself to the Schrödinger equation, sx and sy just do not have values.
Maaari naming sabihin na kapag ang estado-vector ay + o - ayon, s z ay pantay sa / 2 at - / 2 ayon, ngunit, kung isa restricts ang sarili sa Schrödinger equation, x at s s y hindi lamang magkaroon ng halaga.
