1. Driven Harmonic Oscillator with an arbitrary driving force:
f(t)=x"+2bx'+w^2 x
Let x(t) be expressed by x(t)= g(t)*exp(a1*t), where a1 is a solution to the characteristic equation a^2 + 2ba+w=0 for the above second order differential equation. Find the ordinary differential equation that is satisfied by G. There's more parts, but I am just really stuck at the first part.
3.I'm not even really sure where to start. I am thinking i have to differentiate x(t) to get x'(t) and x"(t). then i plug that back into the original differential. is that correct?
