Hi,
I do not know how to drive an experession for energy loss of damped oscillator.I know that:
X(t)=A exp(-Beta*t)cos(wt-delta)
and:
v=dx/dt...
I found E=K+U
but it seems to be so messy. It is like:
E=(1/2)*m*(A^2)*exp(-2*beta*t)[ beta^2 (cos(wt-delta))^2)+beta*
sin 2(wt-delta)+w^2 ]
I do not know if it is right or not but also I do not know how to get the energy loss from it.
I will thank for help.
