Pspice simulation

I'm using version 9.2 for Orcad but I doubt it makes a huge difference for newer versions.
The problem is attached.

I am able to draw the schematic on pspice. I create an AC Sweep simulation with
starting frequency: .01
ending frequency:1,000,000
Logarithmic Decade:100.

I run the simulation and I can do part(a) easily because the resistor is connected to ground. I add trace DB(V(R1:1)). Plot a new y-axis and then add trace VP(V(R1:1)).

My problem is, I don't know what the expression is for part(b) and part(c).

Is VDB across the inductor,
DB(V(L1:1) -V(L1:2))
or is it
[DB(V(1:1)) - DB(V(L1:2))]
or am I doing everything wrong?

you will get the log of the two voltages divided if you subtract the log of two voltages.

So, I think the correct traces should be
DB[V(L1:1) - V(L1:2)]
P[V(L1:1) - V(L1:2)]

is this correct?
