Equation's symbols or parameters description are shown below, however, the = and the details of parameter are not aligned.     I want to make a parameters list for a equation like this, in which symbols, = and detail information are aligned in terms of vertical position.  where    ...    P   =   notional permeability factor    N   =   number of waves    Sd  =   damage level    ...   A tabular environment will produce more spacing before and after text. So how to make the = vertical aligned?   The codes is provided:  \begin{equation} \frac{H_s}{\Delta D_{n50} } = 1.0~ P^{0.13}~ \left(\frac{S_d}{N} \right)^{0.2} \xi_m^P~ \sqrt{\cot \alpha} \end{equation} where:   $H_s$ = significant wave height, equal to the average of the highest 1/3 of the waves  $\Delta$  = relative buoyant density, equal to $\rho_r / \rho_w - 1$, where     $\rho_w$ is the water density  $D_{n50}$ = nominal  diameter defined in Equation (2)  $P$ = notional permeability factor  $S_d$ = damage level   $N$ = number of waves  $\xi_m$ = breaker parameter based on mean wave period $T_m$  $\alpha$ = slope angle

I am using   \begin{equation} a = b \end{equation}   to write the equations in my paper. However, the problem is that the number related to each equation is not shown in the correct format like the picture   How can I fix this?  This is what I have at the first of my code:  \usepackage{graphicx} \usepackage[justification=centering]{caption} \usepackage{float} \usepackage{url}% typeset urls \usepackage{times} \usepackage{url} \usepackage{latexsym} \usepackage{fontspec} \usepackage{multirow} \usepackage{listings} \usepackage{setspace} \usepackage{listings} \usepackage{fontspec} \usepackage{amsmath} \usepackage{polyglossia} \usepackage{color} \usepackage{bidi} \newfontfamily\faFont[Script=Arabic]{Yas}  \newenvironment{Fa}{\begin{RTL}\faFont}{\end{RTL}} \newcommand{\fa}[1]{{\faFont\RL{#1}}} \newcommand\Mark[1]{\textsuperscript#1} \definecolor{backcolour}{rgb}{0.95,0.95,0.92} \definecolor{darkblue}{rgb}{0.95,0.95,0.92} \setmainlanguage{english} \setotherlanguage{farsi} \newfontfamily\farsifont[Script=Arabic]{Yas}

Equation exceeds one column of IEEE pattern in LaTeX how should I correct it? Please help, the code is attached herewith.  \begin{equation}\label{eq11}         p\left( {v,h|u,y,...} \right) = {\rm{RelU}}\left( {\left[ {\hat b + {w^h}\left\{ {\left( {{v^T}{w^v}} \right) \circ \left( {{y^T}{w^y}} \right)} \right\}} \\ \right]*\left[ {\hat a + {w^v}\left\{ {\left( {{h^T}{w^h}} \right) \circ \left( {{y^T}{w^y}} \right)} \right\}} \right]} \right) \end{equation}

Below is an example of an asymmetrical limit (or uncertainty)  How can I typeset this in a \LaTeX equation? Such pair of numbers should be vertically stacked while being vertically center-aligned with rest of the equation. Solution $X^{+Y}_{-Z}$

I want to be able to  write the following in LaTeX      We make the further assumption that \begin{equation} \label{eqn:assumption} There is a bounded linear operator     $B:X\to X^*$ such that $B^*=B$ and the operator $JB$ is an extension of $T'(0)$\end{equation}   and get a nice output, in such a way that this whole chunk of text along with the math can be referenced later. Of course I can write text inside the equation environment using \text{}, but when I tried this the spacing was all wrong. Can anyone suggest a solution to this?

How do I insert the line "|" after the equation in LaTeX (see image below)? I'm using LyX so if you can point me to the symbol of that line is also OK.    I don't know if this line has a proper name so the title of this question may be very vague. If you could provide me a name, I'll edit this question's title.

I was wondering what the proper LaTeX code would be to display something like this:    You don't have to include the mathematical symbols, what is important is the structure.

In LaTeX align, I'm struggling to align polynomial terms and assume there's an easy way to do it. But I cannot find the simple/elegant solution. What I would like is something like this:  x1 + x2 ______________ = 3  x1_______________+ x3  = 4  etc with more lines and variables (the underlines are just for space/alignment). Any help appreciated.  UPDATE Here is the solution I found:  \begin{alignat*}{7} 8x_1 &amp;{}+ 4x_2 &amp;{}+ y_1   &amp;        &amp;        &amp;        &amp;= 160     \\ 4x_1 &amp;{}+ 6x_2 &amp;          &amp;{}+ y_2 &amp;        &amp;        &amp;= 120     \\ x_1  &amp;         &amp;          &amp;        &amp;{}+ y_3 &amp;        &amp;= 34      \\ \phantom{{}+{}x_1}&amp;{}+x_2&amp;&amp;        &amp;        &amp;{}+ y_4 &amp;= 14      \\ x_1\geq0&amp;x_2\geq0&amp;y_1\geq0&amp;y_2\geq0&amp;y_3\geq0&amp; y_4\geq0 \end{alignat*}   with result:

How do I put big brackets under different parts of an equation so that I can write, e.g., text specific to these parts? For example: f =  x^3 +  2     |___|  |__|        |     |    text 1  text 2

The follwing LaTex lines don't print out what I hope to see:  calculate $\rho_i^{t} = \| \mathcal{w}_{i}^{t} - \mathcal{w}_{i}^{t-1} \|_2$   what I get instead of the two w is that:    Can anyone help me please?  Thank you!

Say I have a figure with two subfloats inserted using the subfig package.  When I reference them with \ref{myLabel} I get this     Figure 3.5a and 3.5b.     But what I want is this:     Figure 3.5(a) and 3.5(b).   How can I add the parentheses?
