Using the solution for problem 4 to determine the initial conditions, find and sketch v(t) for all t. 

4.
6 A
In the circuit below, assume the switches are ideal and resistances R₁ and R₂ are
unknown. Find the currents in L₁ and in L₂ just before the switches open,
izi(t = 0) and iz2(t = 0), respectively. Also, find the voltage across both induc-
tors just before the switches open, v(t = 0). Hint: assume that i and i are time
varying at first, ultimately settling down to the given dc values, and that the circuit
is in de steady state before t = 0.
