Graphics, Figures & Tables ⇒ Auto break long math equation

[ponilavarasu]

Hi all, i am new to latex development. Is it possible to auto break a long math equation in latex.? Is there any suitable package/commands? Kindly share if any!

Welcome to the forum!

The breqn package can auto-break equations for you.

Dear Stefan Kottwitz,
Thanks for your reply. I have tried it, and it never break down any equation. Here, we are using double column job and the following eqn not fit and auto break in single column. I simply wrote a math eqn for your reference.

\usepackage[]{breqn}
\begin{equation*}
CFA=\frac{\partial \left(CTh(D)\right)}{\partial z} \mathop{\int} \limits_{0}^{D} \left(\uplambda _{234} \times Def(z)\right)dz+\uplambda _{234} \times Def(D)\times CTh(D)
\end{equation*}

Take a look at the manual, it provides new environments dmath and dmath* for equation and equation*, simply replace:

\usepackage{amsmath}
\usepackage{upgreek}
\usepackage{breqn}
\begin{document}
\begin{dmath*}
CFA=\frac{\partial \left(CTh(D)\right)}{\partial z} \mathop{\int} \limits_{0}^{D} \left(\uplambda _{234} \times Def(z)\right)dz+\uplambda _{234} \times Def(D)\times CTh(D)
\end{dmath*}
\end{document}

By the way, math operators are usually written upright. I would use

Code: Select all

Code, edit and compile here:

\usepackage{amsmath}
\DeclareMathOperator{\Def}{Def}
\DeclareMathOperator{\CTh}{CTh}

and then use \Def and \CTh in the equations.
