prove the idendity [tex] \sigma \times \sigma =i \sigma [/tex] where [tex] \sigma[/tex] is Pauli Spin matrices
The Attempt at a Solution
This is how I did..and I am getting
2[tex] i \sigma [/tex] instead of [tex] i\sigma [/tex].
This question was asked twice for the university exam, and during both times, they asked us to prove [tex] \sigma \times \sigma =i \sigma [/tex].
Did i make any mistake? or the examiner was wrong?
Thanks in advance.
