Enlighten him.

        I'm seeing n and i used as variables in Rudin, predominantly n though, but Im accustomed to n being a constant.

        I've seen it used very frequently as a name for a variable, the imaginary unit i usually has a different typeface to distinguish the two is what Im accustomed to.
