I've recently started my second course in Quantum Theory and am now often required to prove more complex commutation relations. I'm aware that the Levi-Civita symbol often makes this sort of thing a lot slicker, but I'm finding it really hard to crack. There are some great answers to individual queries relating to it online, but I was wondering if anyone knew of somewhere (book, site etc.) I could learn how to use it from the ground up? Maybe with exercises/solutions?
