A system with j = 35 is in the state |ψ⟩= 1/√2 |35,35⟩ + 1/2 |35,34⟩ − 1/2 |35,−20⟩. The state is written in |j,m⟩ notation (m is the Jz projection).

Find ⟨Jz⟩ and ∆Jz for this state. Find ⟨Jx⟩ and ∆Jx for this state.

(Note: This must be done by hand with all work shown; also do this in bracket notation instead of working out the matrices)
