Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

I'm neither a physicist or a mathematician, so I'm having a bit of trouble understanding commutative properties of operators. Here is an example question, if anyone could help show me how to solve it, it would be greatly appreciated.

Show that Lz commutes with T and rationalize that in atoms, wavefunctions are eigenfunctions of Lz. Lz is given, but T is not. T may refer to a previously used kinetic operator for HeH^{+}, or it may just be a general kinetic operator.

Lz = - i*hBar(x*d/dy - y*d/dx)

Given an actual wavefunction, I could solve this (I think), but I don't have a clue what to do without one.

Thanks
