I'm not completly sure but, these are true when the signal is regular 
and periodic.

If you have a "strange" wave, you get a time-variant rms wave. Look a 
example on top of page 3 in this PDF:

(plot RMS(i(r)))

Sincerily, I thought that this are more usual, but there are very few 
references on web and nothing in how to obtain in "free world" (at 
least, I can't find it).

Best regards.

Salud y Revolución.
