I use this sheet quite often to get a rough idea of values. I've grown to depend on it, actually!
It works for capacitor impedance, inductor impedance, or both for resonant frequencies, as well as impedance at various frequencies.
Save it and print it out. I find two thin and transparent rulers are very handy with this as well. It's sort of a 2 dimensional slide rule.
Print it out, and you can also obviously draw on it for each solution for "back of napkin" thoughts without playing with a calculator.
It is log/log/log/log, with the marked line bold, and the middle line slightly bolder. Use two diagonals and two horizontal depending on what you are trying to calculate:
Inductor reactance/impedance at frequency
Capacitor reactance/impedance at frequency
Resonant frequency of capacitor and inductor
