Homework Statement



[S2 total, Sz ∅1]


Homework Equations



S2 total = S2∅1+ 1∅S2+2(Sx∅Sx+Sy∅Sy+ Sz∅Sz)


The Attempt at a Solution


I calculated it in steps:
(1∅Sx 2 +Sx 2∅1) * Sz ∅1
=[S2x, Sz] ∅1 + Sz∅Sx 2
=-h_cut i (SxSy+SySx)∅1 + Sz∅Sx 2

Is it correct way of doing it? I mean I just did one small segment of it. There is still a lot of calculation to be done. Is there any short method?
