Okay so I did out the matrix math a little further, found some more double angle identities and so forth, and if I set \phi to 0 after multiplying through it comes out to σ3 which is what I want for Sz. I think that this is because the unitary operator has to keep the inner product and its...

Homework Statement This is from my first-quarter graduate QM course. Part 4 of this problem asks me to compute the unitary operator U which transforms Sn into Sz, where Sn is the spin operator for spin 1/2 quantized along some arbitrary axis n = icos\phisinθ + jsin\phisinθ + zcosθ.Homework...
