# Aligning minipages in math environment! [closed]

I am wondering why the mathematic lines and the text in the first minipage are not aligned the same.

I would prefer the text part (below the first math part, equation (89)) to extend to the place where the first line of the equation 89 is located.

The code:

\documentclass[a4paper,12pt, reqno]{amsbook}
\usepackage[overlay]{textpos}
\usepackage{graphicx}
\graphicspath{F:/(some path here)/pdfs/}
\usepackage{setspace}
\usepackage{caption}
\usepackage{bm}
\usepackage{cancel}

\newcommand{\e}{\mathbf{e}}
\newcommand{\parn}[1]{\left({#1}\right)}
\newcommand{\p}{\partial}
\newcommand{\strain}{\bm{\varepsilon}}
\newcommand{\brak}[1]{\left[{#1}\right]}
\newcommand{\bff}[1]{\mathbf{#1}}

\begin{document}
\frontmatter
\mainmatter
\noindent
\begin{minipage}[t]{\textwidth}
\begin{minipage}[t]{.58\textwidth}% [t] means top
Then nabla is applied from the left
{\small\begin{align}
\nabla\times\strain\times\nabla &= \parn{\e_1\p_1 + \e_2\p_2 + \e_3\cancel{\p_3}}\times\brak{x_2\e_1\e_3+x_1\e_2\e_3}\notag\\
&=\p_1\parn{x_1}\e_3\e_3 - \p_2\parn{x_2}\e_3\e_3 = \bff{0}\quad \surd
\label{eq:}
\end{align}}
Michell-Cesaro formula; which is a path integral; is path independent for compatible strain fields therefore we take the simplest integration path\;(Fig. 6)
\end{minipage}%<- This is obligate
\hspace{0pt}
\begin{minipage}[t]{.4\textwidth}%
\vspace{0pt}%<- Fake line
\captionsetup{font=scriptsize}
\centering
\includegraphics[width=0.7\textwidth]{sol10c.pdf}%[width=0.48\textwidth]
\captionof{figure}{Inetgration path.}
\label{fig:digraph}
\end{minipage}
\end{minipage}
\end{document}

One does not need textpos package here. And the X_1 in the image should be neglected. – Vahid Nov 24 '12 at 16:25
What "text part" are you referring to and which "mathematic line"? There two of each... including an image! – Werner Nov 24 '12 at 16:27
Please, make a compilable example: nobody knows what \strain and \parn mean. On the other hand it simply seems that the first line in equation 89 is overfull and the unique remedy I see is to make more room for it by enlarging the minipage. – egreg Nov 24 '12 at 16:36
What are \strain, \parn, \p, \e, \brak? How are they defined or what package provides them? – Gonzalo Medina Nov 24 '12 at 16:36
@Vahid Why don't you try to compile your example before submitting it? It doesn't compile because some packages are missing. – egreg Nov 24 '12 at 16:43
