Questions & Answers
how those weight effect a stable motion at equilibrium
how do I differentiate this equation A sinwt with respect to t
just use the chain rule : let u =wt , the dy/dt = dy/du × du/dt : wA × cos(wt)
Jerry
I see my message got garbled , anyway use the chain rule with u= wt , etc...
