Inline Limit Rendering

| Comments |


In the past, I know two ways of writing a limit using $\rm \LaTeX$.

  1. $\lim_{x \to 1} \frac{1}{x^2}$ looks OK.

     $\lim_{x \to 1} \frac{1}{x^2}$
  2. $\displaystyle \lim_{x \to 1} \frac{1}{x^2}$ looks better, but it occupies more than one line’s vertical space.

     $\displaystyle \lim_{x \to 1} \frac{1}{x^2}$

For option (1), including limits in inline equations by _ doesn’t look good since $x \to 1$ isn’t placed at the bottom of $\lim$.

If we want the text to occupy less space to save paper, then option (2) isn’t good. In order to see another drawback of this option, I have written some long (and meaningless) sentences here, so that the fraction in this paragraph appears in the middle. Although I seldom write in English, I have tried my best to illustrate my ideas with words. The vertical space created by the fraction in display style $\displaystyle \frac{1}{x^2}$ doesn’t match with the line separation of other lines in the paragraph. If you have already reached this line but you don’t understand what I’m saying, I’m write more so as to wrap the fraction with a chuck of text.


To create an inline limit $\lim\limits_{x \to 1} \frac{1}{x^2}$ which looks better in the middle of a paragraph. Fames ac turpis egestas. Duis ultricies urna.

Use \lim\limits_{x \to 1} \frac{1}{x^2} instead.
