How can i write the fractions in 1) so the numerator and denominator have the same height as the non-fraction in 2)

I'm using:

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

$2.\; \displaystyle{\lim_{x \to 0}}$ $\tan(x+\pi/4)$  \\

enter image description here

  • Welcome to TeX.SE! Are you looking for \displaystyle? – user121799 Jan 14 '19 at 23:50
  • Welcome to TeX SX! Why do you split each line into two math groups? – Bernard Jan 14 '19 at 23:50
  • Change $1.\; \displaystyle{\lim_{x \to 1}}$ $\frac{x^2}{x-2}$ to $1.\; \displaystyle{\lim_{x \to 1}}\frac{x^2}{x-2}$. (i.e. remove the two $ in the middle). Actually, you should do this for both 1 and 2 anyway :-) – whatisit Jan 14 '19 at 23:51
  • ty, i had added it - what is the best way to add a small space between the limit and the fraction? – buffalo Jan 15 '19 at 0:13
  • Note that \displaystyle, if used correctly, will have two effects: (i) the fraction term will be typeset differently and (ii) the argument of \lim will be placed below rather than to the lower-right of "lim". – Mico Jan 15 '19 at 3:20

This should work, but isn't well coded. Are you tring to do an enumeration of maths formulæ?

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

$2.\; \displaystyle\lim_{x \to 0}\tan(x+\pi/4)$  
  • ty, i had added the $ $ for a small space - what is the best way to add a small space between the limit and the fraction? ty – buffalo Jan 15 '19 at 0:14
  • Normally it is all taken care of by the system. If think it's as fine as you'd like, you may add a tin unbreakable space (\,) between the limit and the fraction. – Bernard Jan 15 '19 at 0:22
  • superb, tyvm works – buffalo Jan 15 '19 at 1:48
  • \displaystyle is a switch, i.e., it doesn't take an argument. – Mico Jan 15 '19 at 2:31
  • @David Carlisle; Yes. 'Tis fixed. Actually, I didn't notice the O.P. used \displaystyle as a command. Thanks! – Bernard Jan 15 '19 at 10:04
