## Homework Statement

I must prove that:

[tex]\frac{d}{dt}<xp> = 2<T> - <x\frac{dV}{dX}>[/tex]

And use the virial theorem to prove that [tex]<T> = <V>[/tex]

## Homework Equations

[tex]2<T> = <x\frac{dV}{dX}>[/tex]

[tex]\frac{d}{dt}<Q> = \frac{i}{h(bar)}<[H, Q]> + <\frac{\partial Q}{\partial t}>[/tex]

Where Q on the

**right side**is an operator, as well as H.

## The Attempt at a Solution

Do I just plug in [tex]\frac{d}{dt}<xp>[/tex] into the general equation?

Thanks.
