Hello! I looked over a proof of Noether theorem and I am a bit confused about the last step. So they got that ##\delta q(t) p(t)## is constant (I just took the one dimensional case here) where ##\delta q## is a variation of the q coordinate and p is the momentum conjugate of q. I am not sure I understand how does this imply that p is conserved (I guess I don't understand very well the meaning of ##\delta q(t) ##). Can someone please explain? Thank you!
