Math & Science ⇒ All new equations generated with the same equation number

[localghost]

Perhaps you should use another environment with additional adjustment of some delimiters.

Code: Select all

\begin{equation}
  \begin{aligned}
    \textbf{Cpl} (0,T_{j-1},T_j,\tau_j,K) &= \tau_j P(0,T_j) \Biggl[\sum_{i=1}^N \psi_i \exp^{-\frac{1}{2} \beta_i^2 t+ \beta_i h_t^{-1}(F_j(t))}\,\Phi\Biggl(\frac{\beta_i(T_{j-1}-t)-h_{T_{j-1}}^{-1}(K)+ h_t^{-1}(F_j(t))}{\sqrt{T_{j-1}-t}}\Biggr) \\
    &\quad -K \Phi\Biggl(\frac{h_t^{-1}(F_j(t))-h_{T_{j-1}}^{-1}(K)}{\sqrt{T_{j-1}-t}}\Biggr)\Biggr]
  \end{aligned}
\end{equation}

The amsmath user guide describes all provided environments in detail. Just choose the one which fits best your ideas.

but it comes out right justified?

you have used split but without column separator &, so all lines are like first columns, those would be right justified. It's a long formula and there could be more improvements, but for the moment here's a multline version:

Code: Select all

\begin{multline}
  \textbf{Cpl} (0,T_{j-1},T_j,\tau_j,K) \\
  \tau_j P(0,T_j) [\sum_{i=1}^N \psi_i \exp^{-\frac{1}{2} \beta_i^2 t+ \beta_i h_t^{-1}(F_j(t))} \Phi( \frac{\beta_i(T_{j-1}-t)-h_{T_{j-1}}^{-1}(K)+ h_t^{-1}(F_j(t))}{\sqrt{T_{j-1}-t}}) \\ -K \Phi(\frac{h_t^{-1}(F_j(t))-h_{T_{j-1}}^{-1}(K)}{\sqrt{T_{j-1}-t}})] 
\end{multline}

Decide, where you want to break the line, and think about enlarging parantheses/brackets.

Perfect that's it!!!

Also I have now corrected all the errors and the numbering issue has been resolved in the process!

Thank you to you all!

[bazman]

ah hold on!

one more thing.

When I use {multiline} in no longer numbers the equation. Is their away so that a numer is generated in line with the numbers when I use {equation}?

[gmedina]

Hi,

the unstarred versions of the environments provided by amsmath produce numbering. Please post here the code that you are using for your multline environment.

[bazman]

So sorry it was my mistake I used typed multiline instead of multline!

Starting to think I have dyslexia!

[phi]

There is no multiline environment, so a code like

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{multiline}
  a = b
\end{multiline}
\end{document}

issues an appropriate error message. You simply mustn't ignore error messages!
