Math & Science ⇒ character of formule more bigger

[allevo]

hi!!!!
i'd want write the formule but the characters are too small...
how can i increase the dimension of character?!?!?

Hi Allevo,

do you mean the size of a math symbol or of a whole formula? Inside text or inside an equation environment or where?

You could write \Huge, \Large etc. before a formula.

If you're worried about the size of all or part of a formula, you can easily wrap the part that's too small in \displaystyle. For example:

$ \displaystyle{\sum^5_{n = 1} n^2} $

If, however, you're worried about your brackets being too small, use the \left and \right commands, i.e.

$$9 \left( \frac{n^2 - n}{5} \right) $$

Please avoid the $$ ... $$ syntax for display math in LaTeX. Let me quote David Carlisle for reasons why:

$$ is TeX primitive syntax, which [...] is hard to redefine (in classic TeX there is no command name which triggers entering or leaving display math).

LaTeX doesn't officially support $$. The most noticeable failure if you use the syntax is that the fleqn option will no longer affect the display of the mathematics, it will remain centered rather than being set flush left.

However if you are using \[ it is best to use the amsmath package (it is best to load this package if doing any serious mathematical layout with LaTeX).

\[ is a short form of \begin{displaymath} which one might expect to act like an un-numbered form of \begin{equation}. The amsmath package redefines \[ to be \begin{equation*} which is exactly an un-numbered form of the equation environment as defined by that package. In the core LaTeX definition \[ has the definition

Code: Select all

\ifvmode
   \nointerlineskip
   \makebox[.6\linewidth]{}%
\fi
$$

which means that the spacing if used between paragraphs is better than a primitive $$ (which causes a blank paragraph just consisting of the indentation and parfillskip glue to be inserted before the display) but it is inconsistent with equation and always uses \abovedisplayskip rather than \abovedisplayshortskip. In the AMS versions the spacing is more consistent
