## Homework Statement

## Homework Equations

Q(t) = Ae

^{i(wt+Φ)}; dQ/dt = i*w*Q(t); E = (L/2)(dQ/dt)

^{2}+ Q

^{2}/2C

i = √-1 E above is average energy

## The Attempt at a Solution

When I plug in Q(t) & dQ/dt into equation above (E) I get:

A

^{2}L/2(w

_{0}

^{2}-w

^{2})cos[2(wt+Φ)]

w

_{0}

^{2}= 1/LC

After I plugged both of them in I simplified & took the real part. Why aren't I getting the answer?
