I have been looking for an answer for some time now, hope you could give me a quick tip.
I have an equation with many divisions inside. i.e:
$\frac{\frac{a_1}{a_2}} {\frac{b_1}{b_2}}$
To make it more readable, I decided to change the large fraction into "/" sign. i.e.
$\frac{a_1}{a_2} / \frac{b_1}{b_2}$
The problem is that the "/" sign remains small, and it is quite ugly.
How do I change the "/" sign to have a big font? How do I make it more readable?
This question is related to
latex
Another option is to use \dfrac instead of \frac, which makes the whole fraction larger and hence more readable.
And no, I don't know if there is an option to get something in between \frac and \dfrac, sorry.
I found the answer I was looking for. The thing to use here is the construct of
\left \middle \right
For example, in this case, two possible solutions are:
$\left( {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right) $
Or, in case the brackets are not necessary:
$\left. {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right. $
A possible soluttion that requires tweaking, but is very flexible is to use one of \big, \Big, \bigg,\Bigg in front of your division sign - these will make it progressively larger. For your formula, I think
$\frac{a_1}{a_2} \Big/ \frac{b_1}{b_2}$
looks nicer than \middle\ which is automatically sized and IMHO is a bit too large.
