Hi,
I am sure I have mistaken my DE setup or my initial conditions assumption.
[URL]http://ivila.net/E8.png[/URL]
R1 will be the middle Resistor
R2 the top one.
i1' + R1/L i1 = R1/L i2
i2(R1+R2)*1/(R1) + 1/(R1*C)*integral(i2)=i1
My initial conditions are i1(0) = 1A
Vl = L di1/dt
at (0+) VL = 0 therefore L di1/dt = 0 therefore di1/dt = 0
i1'(0) = 0
Substitute for i1 I end up with sqrt(2)exp(-2)cos(t+45')
