>>9836454
I'm reading up on Feynman path integrals over the summer before my masters' in QFT, but for now my best bet is you apply a variational principle to the quantum action just like you would for a classical system. So like take the derivative of the path integral of the action. It's actually pretty straightforward if the equations cooperate.

Why are undergrads always so enthusiastic about showing off their ignorance? Is it the tap water?
