## PHYS208 Fundamentals of Physics II

### Answer for Ch. 33, 36P

Substitute this derivative and the one from the hint into Eq. 33.20 to find the
final expression.

b) Beta is 11.4 rad/sec and omega is 176 rad/sec.
When beta is much smaller than the omega, the fractional shift introduced by loss
can be approximated by -(beta/omega)^{2}/2.
Thus the fractional shift in frequency is 0.2%.
