I tried all that, everything I could think of, before posting. This is what
LTSPICE is showing me for the calculated impedance graph (red) and I don't
really know why. If I punch those numbers (the red graph's equation) into a
calculator, I get expected values for the capacitor's impedance. But for
some reason, the graph looks really strange with really odd values in
LTSPICE. The green and blue graphs look fine though.
