Math & Science ⇒ Math Mode Font Size too small at certain Places

[julianinblack]

Hi everybody,

I have a problem with my equations. For information, I am using Lyx. The problem is that in the 'cases' environment (basically it's juste an array with a parenthesis), the size of the police is automatically fitted (I think it's just like for a normal equation in fact). It means that if I write a fraction with for example a square root and then inside another fraction, the final letters will be so small that you can barely read it (this is the 'scriptscriptstyle' size). I think it's a general problem, but I haven't find any information about that. So, I would like to disable this automatic fit, so that all the letters in my formula are written in the 'displaystyle' size, even if there is a very complicated formula with fractions etc.
Thanks.

Julian

Here is an answer ...

The only problem is that the size of subscripts and exponents will be affected directly by it, because for a \displaystyle size text, the subscript will be \scriptstyle size. Any solution ?

Hi Julian,

welcome to the board!

You could use the command \displaystyle, you could also repeat it within nested expressions:

Code: Select all

$\displaystyle\frac{x}{\displaystyle\frac{y}{\sqrt{2}}}$

This causes \displaystyle to be called for each inline expression, still you would have to call it in nested expressions:

Code: Select all

\everymath{\displaystyle}
