You are simply taking the wrong quadrant when using the arctan of phi! Of course, the phase shift varies CONTINUOUSLY and does not "hop" by an amount of pi when the driving frequency reaches the characteristic frequency. The response is always lagging as you can find in any elementary book on mechanics. Instead the tan^-1 key on your calculator does the hopping for it cannot know in which quadrant your argument is located... you're really a grad student in elementary particle physics??? | |
