Consider the following system of differential equations for the currents i2(t) and i3(t) in the electrical network shown in the figure above: d/dt(i2(t)) = -R1/L1 * i2(t) - R1/L1 * i3(t) + E/L1 d/dt(i3(t)) = -R1/L2 * i2(t) - (R1 + R2)/L2 * i3(t) + E/L2 Use the method of undetermined coefficients to solve the system if R1 = 3 ̄, R2 = 8 ̄, L1 = 1 H, L2 = 1 H, E = 90 V, i2(0) = 0, and i3(0) = 0. (b) Determine the current i1(t).
