Question

The current i(t) in a simple electric circuit is modeled by the differential equation d +Ri = E(t) where time L is inductance and E(t) is the voltage at time t. Using the method of undetermined coefficients, determine the charge, 4(t), at any time t, given that L = 4,R = 12, E(t) = 4sin(2t) , i(t) = d9 and that the initial current and charge is zero [15]
