So folks, I'm learning complex analysis right now and I've come across one thing that simply fails to enter my mind: the Cauchy Integral Theorem, or the Cauchy-Goursat Theorem. It says that, if a function is analytic in a certain (simply connected) domain, then the contour integral over a simple...
Homework Statement
Show that the ratio of two successive maxima in the displacement of a damped harmonic oscillator is constant.(Note: The maxima do not occur at the points of contact of the displacement curve with the curve Aeˆ(-yt) where y is supposed to be gamma.

Hey @Chestermiller sorry it took so long for me to reply, internet access here is a bit precarious. I understand the derivation of this relation first decomposing the vectors into its components, and then differentiating it with relation to time, but the approach taken in the book (and the...
