do you mean A/ root 2 ? like for sine waves?

First you SQUARE the value of the amplitude of the wave. In this case you get the absolute DC value of amplitude (remember squaring a negative number makes it positive).
Then, you take the MEAN, which in this case is the constant DC value of the amplitude (squared).
Finally you take the ROOT of that value, which gives you the original amplitude. That's your RMS value -- the absolute value of the DC amplitude of the wave. Like the guy above says... trivial.

Rms Of Square Wave

I don't think it is so trivial. If you define your waveform like for digital logic voltages, 5 volts on, 0 volts off, then the RMS is the "on" voltage times the duty cycle. For the special case of the on/off being the same time duration, then duty cycle is 0.5 and the RMS voltage is half the "on" voltage. In the pre-computer days, every car had a 5 volt precision regulator for the analog instrument gages. The duty cycle of a square wave chopper was adjusted to get exactly 5 volts RMS from the car battery voltage..

for square waves RMS=peak

Well, obviously, you simply apply the formula for RMS voltages. In this case it is rather trivial...
