# Large vertical brackets for limits of definite integrals.

How do I make a large vertical bracket for definite integrals like this one? $|_0^t$

Is there a link to a page containing tags for all symbols? I have looked and my page search never lists one although I am certain one exists because I have seen it before.

Another option, though it doesn't automatically change its size, is to use \bigl|. You can manually change the size by using \bigl|, \Bigl|, \biggl|, \Biggl|, as in $$\bigl|, \Bigl|, \biggl|, \Biggl|$$ Replacing l by r allows you to make right-justified symbols (this only changes the spacing in relation to the objects around it), and change | to any of (,),],[,\{,\} allows you to do the same with those symbols as well.

• You can also use \bigr and so on, which is spaced to fit just to the right of something. Here's \biggl and \biggr: $$\frac{x^2-1}{x} \biggl|_1^2\qquad\frac{x^2-1}{x} \biggr|_1^2$$ Looks like no difference in this case. Feb 18 '15 at 14:10
• Yes, I pointed out that possibility in my answer, but it's probably best to give an example, as you did. The difference is extremely minute, however (looks to me like a pixel or two). Feb 18 '15 at 14:31

You want the code \left. {}\right|_{}^{}. The dot after \left makes the left delimiter not appear. In general \left \right gives self adjusting delimiters. For example, \left. \frac{x^2-1}{x} \right|_1^2 gives $$\left. \frac{x^2-1}{x} \right|_1^2$$

• I like your answer but I also need the lookup page which contains tags for all symbols in Tex. Do you have it? Feb 18 '15 at 3:20
• @JulesManson In the search page, input "TeX tutorial."

• Thank you Pedro. My question was satisfactorily answered and I closed the post with a green checkmark. Feb 18 '15 at 3:29
• The green checkmark is not "closing the post" but "accepting the answer". That was the proper thing to do if it answered your question. Feb 18 '15 at 14:11
