Show explicitly using Pauli matrices that the S^{2}operator is diagonal in the second basis.

2. Relevant equations

S^{2}=S[tex]^{2}_{1}[/tex]+S[tex]^{2}_{2}[/tex]+2S[tex]_{1}[/tex]S[tex]_{2}[/tex]

3. The attempt at a solution[/b]

In the last term, 1 and 2 are supposed to be subscripts, and the two S's should be shown as a dot product.

Treat as a 2-particle system; what are they looking for? What does "in the second basis" mean? There is also a chance that the probelm statement is incorrect; in the instructor's superscripts, it's often impossible to distinguish a 2 from a z. Thanks in advance.
