Where did the integral in your first step come from? Start with the definition of [itex]\langle \hat{P} \rangle[/itex]...View attachment 51114
the attachment shows my work. I honestly think maybe i did something wrong. at any rate the integrand is 1 and so not really even or odd.
any help is appreciated
The average linear momentum of what state?Sorry, I am supposed to calculate the average linear momentum.
So would be <p> =∫ψ*(x)P(hat)ψ(x)dx
P(hat) = -ih(bar)(d/dx)
Does [itex]\frac{\infty}{\infty}=1[/itex]? That is essentially what you are claiming in your last step.
