How can I change the size of equation?
2,378
I can only repeat my answer to your previous post, with this concrete example.
Apart from the size problem, your code is excessively complex: you don't need all these \left … \right
pairs.
Besides, there is a cases
environment, inside which formulae are typeset in \textstyle
. If it is too small for your needs, you can use the medium-size commands and environments from nccmath
. Finally I added the dcases
environment from mathtools
(an extension of amsmath
) which typesets its content in \displaystyle
:
\documentclass{article}
\usepackage{mathtools, nccmath}
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.3pt}
\begin{document}
\begin{equation*}
\begin{dcases}
{-\frac{2S_{1}^{f}( \mathbf{z}_{(j,l,m) }) + S_{1}^{2f}( \mathbf{z}_{(j,l,m)}) +2f}{2f( f+1) }}, & {y i ∈ UC_{( j,l,m) }}
\end{dcases}.
\end{equation*}
\begin{equation*}
\begin{cases}
{-\mfrac{2S_{1}^{f}( \mathbf{z}_{(j,l,m) }) + S_{1}^{2f}( \mathbf{z}_{(j,l,m)}) +2f}{2f( f+1) }}, & {y i ∈ UC_{( j,l,m) }}
\end{cases}.
\end{equation*}
\begin{equation*}
\begin{cases}
{-\frac{2S_{1}^{f}( \mathbf{z}_{(j,l,m) }) + S_{1}^{2f}( \mathbf{z}_{(j,l,m)}) +2f}{2f( f+1) }}, & {y i ∈ UC_{( j,l,m) }}
\end{cases}.
\end{equation*}
\begin{equation*}
\begin{dcases}
{-\frac{2S_{1}^{f}( \mathbf{z}_{(j,l,m) }) + S_{1}^{2f}( \mathbf{z}_{(j,l,m)}) +2f}{2f( f+1) }}, & {y i ∈ UC_{( j,l,m) }}
\end{dcases}.
\end{equation*}
\end{document}

I have the following equation:
\begin{equation*} \left\{ \begin{array}{ll} {\small -\dfrac{2S_{1}^{f}\left( \mathbf{z}_{\left( j,l,m\right) }\right) + S_{1}^{2f}\left( \mathbf{z}_{\left( j,l,m\right) }\right) +2f}{2f\left( f+1\right) }}, & {\tiny i\in UC_% _{\left( j,l,m\right) }} \end{array} \end{equation}
This equation is very wide and I want small it. How can I do it?
The code
{\small $some formula$}
works for the formula among the text.-

in math mode. -
Fahim B almost 7 years@Mico what are the math form for these code?
-
Bernard almost 7 yearsYou already asked the same question. None of the answers was useful?
-
Mico almost 7 yearsIsn't this a repeat of your earlier question?
-
Bernard almost 7 years@Mico: With a concrete example, now.

Fahim B almost 7 years@Mico Thank you. you are right, this question is repeat of my earlier question. I used the same method that you proposed for past question and it worked.
