I think this equation will fit into one line, but I'm running out of space in the editor. I don't want to split the equation (I don't think I will need to)

\begin{subequations}
\begin{align}
\nu_{p} 
& =\frac{\partial V_{c}}{\partial \sigma_{p}}\\
&=PN'(d1)\frac{\partial d1}{\partial \sigma}\frac{\partial \sigma}{\sigma_{p}}\\
&\ -GHN'(d2)\frac{\partial d2}{\partial \sigma}\frac{\partial \sigma}{\partial \sigma_{p}}
\end{align}
\end{subequations}

any suggestions? Thanks!

  • Could you include a MWE? Otherwise, we cannot judge whether it will fit on one line. – Karlo May 30 '17 at 15:18

    Hi Karlo - relatively new to this. I posted the equation that I'm trying to write...not sure how to create a MWE. I'll explore that. – Chet May 30 '17 at 15:27
  • AboAmmar - that's perfect; worked great, thanks sir! – Chet May 30 '17 at 15:29
  • A MWE (minimal working example) means a complete piece of code that we can run to see the problem. If you only give the code \begin{subequations}...\end{subequations}, we do not know if we will have the same result if we add a documentclass etc. And it just saves time. – Karlo May 30 '17 at 16:59

I'm not sure what you mean by running out of space in the editor, you can write the equation on as many lines as you want in the editor not leaving blank lines.

\begin{align}
\nu_{p} &=\frac{\partial V_{c}}{\partial \sigma_{p}} \notag\\
&=PN'(d_1)\frac{\partial d_1}{\partial\sigma}\frac{\partial\sigma}{\partial\sigma_p}-GHN'(d_2)\frac{\partial d_2}{\partial\sigma}\frac{\partial \sigma}{\partial\sigma_p}
\end{align}

Yes, it all fits in one line. I also suggest you simplify typing partial differentials with the \diffp command, from esdiff.

\documentclass{article}
\usepackage{mathtools, esdiff}
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.3pt}

\begin{document}

\begin{subequations}
  \begin{align}
    \nu_{p}
    =\diffp{V_{c}}{{\sigma_p}}
    =PN'(d1)\diffp{d1}{σ}\diffp{σ}{{\sigma_p}}
    \ -GHN'(d2)\diffp{d2}{σ}\diffp{σ}{{\sigma_p}}
  \end{align}
\end{subequations}

\end{document}
