2.) (a) Prove that q(t) = e-Yt (A cos wt + B sin wt) used in the RLC closed circuit differential equation gives the equation f cos wt +g sin wt = 0 with the constants f and g in the the form of functions w, y, A, and B! (Please explain step-by-step clearly!) (b) In the initial conditions q(0) = q0, we get A = q0. In another initial condition, that is when t 0, the current is zero (the inductor acts as if it were an infinite resistor right after the switch is closed) and it's written as follows: dq i(0) dt With some of the conditions above, and that holds f cos wt + g sin wt = 0 if f = g = 0, Determine B, w, and y! (Please explain step-by-step clearly!)

2.) (a) Prove that q(t) = e-Yt (A cos wt + B sin wt) used in the RLC closed circuit
differential equation gives the equation f cos wt + g sin wt = 0 with the constants f
and g in the the form of functions w, y, A, and B ! (Please explain step-by-step clearly!)
(b) In the initial conditions q(0) = qo, we get A = qo. In another initial condition, that is
when t = 0, the current is zero (the inductor acts as if it were an infinite resistor right
after the switch is closed) and it's written as follows:
da
= 0
dt
With some of the conditions above, and that holds f cos wt + g sin wt = 0 if f = g = 0,
Determine B, w, and y ! (Please explain step-by-step clearly!)
