I'm using the following packages:



usepackage{mathrsfs}
usepackage{mathtools}
usepackage{amsmath,latexsym}


in order to write the following equation.



begin{eqnarray*}
frac{partialmathscr{L}}{partial(partial_nu A_mu)} =-frac{1}{4} left[
left(frac{partial(partial_sigma A_omega)}{partial(partial_nu A_mu)}
-frac{partial(partial_omega A_sigma)}{partial(partial_nu A_mu)}right)
(partial_alpha A_beta-partial_beta A_alpha)
+ (partial_sigma A_omega - partial_omega A_sigma)
left(frac{partial(partial_alpha A_beta)}{partial(partial_nu A_mu)}
-frac{partial(partial_beta A_alpha)}{partial(delta_nu A_mu)}right)
right]
end{eqnarray*}


The problem is that the equation is too long for a single line. When I try to break it on the "plus" sign, it no longer recognizes the last right] command, and my brackets do not close. I Checked the code several times, it seems correct.



Any Ideas?

For the sake of completeness I'd like to suggest an automated solution using breqn. It can break a display math equation respecting left and right delimiters. An example without any change inside the formula:



documentclass{article}
usepackage{amsmath}
usepackage{mathrsfs}
usepackage{breqn}
begin{document}
begin{dmath*}
frac{partialmathscr{L}}{partial(partial_nu A_mu)}
=-frac{1}{4}left[left(
frac{partial(partial_sigma A_omega)}{partial(partial_nu A_mu)}
-frac{partial(partial_omega A_sigma)}{partial(partial_nu A_mu)}right)
(partial_alpha A_beta-partial_beta A_alpha)
+ (partial_sigma A_omega - partial_omega A_sigma)
left(frac{partial(partial_alpha A_beta)}{partial(partial_nu A_mu)}
-frac{partial(partial_beta A_alpha)}{partial(delta_nu A_mu)}
right)right]
end{dmath*}
end{document}


The result mimics multline:

  • All answers really were really helpfull! Ended up using the {dmath*} enviroment becouse it was more convenient for the rest of the code. I like to use left and right, it feels more organized. I think it scales automatically with the size of the rest of the terms. Thank you, guys! OBS.: About my equation: I forgot about the metric tensor eta^{alphasigma}eta^{betaomega} after the fraction 1/4. The rest shoud be all right!

    You wrote,




    I Checked the code several times, it seems correct.




    Actually, it is not correct: TeX syntax rules do not allow line breaks inside a left[...right] group. The solution is not to use left and right to begin with. Instead, do use biggl[ and biggr].



    Here's a solution which uses an align* environment -- please don't use the badly deprecated eqnarray* environment -- and rearranges the multiplicative terms in the second row so that than can be aligned with the corresponding terms in the first row. And, all auto-sizing directives have been replaced with the explicit-sizing instructions biggl and biggr.



    enter image description here



    documentclass{article}
    usepackage{mathrsfs} % for 'mathscr' macro
    usepackage{mathtools}
    usepackage{%amsmath, % is loaded automatically by 'mathtools' package
    amssymb} % not 'latexsym'!

    begin{document}

    begin{align*}
    frac{partialmathscr{L}}{partial(partial_nu A_mu)}
    =-frac{1}{4} biggl[
    &biggl(frac{partial(partial_sigma A_omega)}{partial(partial_nu A_mu)}
    -frac{partial(partial_omega A_sigma)}{partial(partial_nu A_mu)}biggr)
    (partial_alpha A_beta-partial_beta A_alpha)\
    {}+{} % make '+' act like a binary, not unary, operator
    &biggl(frac{partial(partial_alpha A_beta)}{partial(partial_nu A_mu)}
    -frac{partial(partial_beta A_alpha)}{partial(delta_nu A_mu)}biggr)

              You wrote,




              I Checked the code several times, it seems correct.




              Actually, it is not correct: TeX syntax rules do not allow line breaks inside a left[...right] group. The solution is not to use left and right to begin with. Instead, do use biggl[ and biggr].



              Here's a solution which uses an align* environment -- please don't use the badly deprecated eqnarray* environment -- and rearranges the multiplicative terms in the second row so that than can be aligned with the corresponding terms in the first row. And, all auto-sizing directives have been replaced with the explicit-sizing instructions biggl and biggr.
