If:
[tex]\delta x^\mu = a^\mu +w^{\mu}_{\nu}x^\nu[/tex]
How would we go about working out
[tex]\delta_1 \delta_2 x^\mu[/tex]
This is apparently equal to:
[tex](w^{\mu}_{1}_\nu a^{\nu}_{2} + w^{\mu}_{1}_\lambda w^{\lambda}_{2}_\nu) x^\nu[/tex]
but I can't understand what is going on with the indices - can someone help me out?
