Construct Notes
Presenting Relations:

$(a \mathrel{\mathcal R} b)$

$(a \mathcal R b)$

As for parentheses, you should be careful because $\lor$, $\land$, and $\lnot$ can have somewhat different meanings that can be confused without parentheses. For example, $a = b \wedge c = d$ could be read as $(a = b) \land (c = d)$ (that is, "$a = b$ and $c = d$", or it could be read as "$a = (b \wedge c) = d$" (that is, "$a$ equals the meet of $b$ and $c$, which also equals $d$). The same problem happens with $\lor$, which looks just like $\vee$, which can mean "join". Note also that $\neg$ may be read as "complement" in some cases, so you have to be just as careful there. --Dfeuer (talk) 07:59, 5 March 2013 (UTC)

I will be extracting some stuff off this if you don't mind:




 * Actually, I'd rather see it coming from some elements from the extensive reference list &mdash; notes like these can perish without warning. If you like the presentation, please make sure to grab a copy of it before it's too late. &mdash; Lord_Farin (talk) 07:40, 5 March 2013 (UTC)


 * Okay :) --Jshflynn (talk) 07:50, 5 March 2013 (UTC)

When did transclusion first appear on this site?
In particular when did it really take off?

There's something oddly pleasing about it.


 * Sometime around when I discovered its use in Trigonometric Identities, around 29th Dec 2010. My playlist at the time was the Beatles 1962-66 and 1967-70 which I'd just bought for the wife for xmas. Can you think of a more pleasurable occupation than doing maths while listening to the Beatles? --prime mover (talk) 21:24, 6 March 2013 (UTC)
