How to put a big bracket under different parts of a equation so that I could write e.g. a text specific to that part in the equation?

Does anyone know how to code the subscript squiggle thing? It looks kind of like

$f_a + f_a + f_a$   
~~~~~~~~~~~~~~~~~  
       f_n

I personally don't know how to explain it. It's used in math. If you have a set of numbers and you put the squiggle underneath them and in the center below the squiggle you put like f_n denoting that the expression above the squiggle is the same as f_n.

It's called an \underbrace. – Werner Jan 25 '13 at 23:51

@Werner Yes, buy how do you insert the text to go under it? – Anthony Peter Jan 25 '13 at 23:54

For example like so: $\underbrace{f(x)}_{\textit{function}}$ – rtzll Jan 25 '13 at 23:56
@AnthonyPeter In your case: $\underbrace{f_a + f_a + f_a}_{f_n}$ – Qrrbrbirlbel Jan 25 '13 at 23:57

@ChristianR.: Using \textit in the argument of \underbrace will not scale to the usual math script fontsize. \text (from amsmath) is better. – Werner Jan 26 '13 at 00:14
What you gotta do, is print the document out, and using a texta, do it by hand. – Nicholas Hamilton Jan 26 '13 at 04:49
