Why Is the RMS Coefficient of a Triangle Wave \(\frac{1}{2\sqrt{3}}\)?

[gulsen]

I've seen some coefficient such as $$\frac{1}{2\sqrt 3}$$ for triangle waves. Who ordered that? How can I derieve it? It doesn't seem to be $$\sqrt{ \frac{1}{T} \int_0^T {V^2 dt} }$$ because I found something like that for triangle wave: $$V_m 2\sqrt 2 f$$ (am I wrong?? or I'm calculating the wrong thing??)

Whoops! Miscalculation! It's $$\frac{V_m}{\sqrt 3}$$. Gotta sleep, I guess...
