As you say, some people use a vertical bar and others use square brackets $\endgroup$ – Hans Lundmark. Only thing diffrent I see are that the numbers are on the right side of the line rather than above and bellow it, but I guess it is acceptable if it is undrstood (as long as my prof agrees, I will find out after couple weeks when this particular excersice I'm working on is due). If so, try this: Code: Select all tion At this point it seems that $\Big/_1 3 \frac{1}{2}x 2 + x$ seems to give me the needed result in simplest code.

[/latex] We use this vertical bar and associated limits [latex]a[/latex] and [latex]b[/latex] to indicate that we should evaluate the function [latex]F(x)[/latex] at the upper limit (in this case, [latex]b[/latex]), and subtract the value of the function [latex]F(x)[/latex] evaluated at the lower The vertical bar or line (|) serves various purposes, from denoting absolute values to separating matrix elements. $\left.

What I would like to do is create a vertical line down the page. . Leibniz's notation makes this relationship explicit by writing the derivative as: [1]. Basically just using | is mostly ok, but I have defined a special purpose command for this, that automatically scales the line vertically: \newcommand\at[2]{\left. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{} and ending with \end{document}. eileenslounge.
