Math & Science ⇒ Unwanted Variations in Equation Alignment

[abikutn]

I don't understand why the variation in the alignment of the math output happens.

Code: Select all

\documentclass[11pt]{article}
\usepackage{color}
\usepackage{amsmath}
\usepackage[square, comma, sort&compress]{natbib}
\author{abhi} 
\title{Simple Document}
\label{Simple document to show different reference typesets}

\begin{document}

 \section{This is how a Referencing section and Math formula should be done!}
 
And below is some math typesetting of \LaTeX

\begin{align}
	 E &= mc^2                              \\
    m &= \frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}
\end{align}

And below is some math typesetting of \LaTeX with the help of mathematica
\begin{align}
	E=\frac {1}{\sqrt{{{v}^{{2}}}}}\\
	E=\frac {1}{\sqrt{{{v}^{{2}}}}}\\
	n_{\text{ave}}\text{  }=\text{  }i_{\text{dark}} \text{$\Delta $t}/e
\end{align}
And below is some math typesetting of \LaTeX with the help of mathematica
\begin{align}
E &= mc^2\\
n_{\text{ave}}\text{  }=\text{  }i_{\text{dark}} \text{$\Delta $t}/e\\
   P[n] \approx  \frac{1}{\sqrt{2\pi } \sigma }e^{\left.-\left(n-n_{\text{ave}}\right){}^2\right/2 \sigma ^{2\text{   }}}\\   
   \sigma _i{}^2 =\frac{n_{\text{ave}} e^2}{\text{$\Delta $t}^2}=\text{  }i_{\text{signal}} \frac{e}{\text{$\Delta $t}} =i_{\text{signal}} e 2B\\
   N_p[t]=\frac{P[t]-P_0}{P_0}= \frac{S[t]^r-S_0{}^r}{S_0{}^r}\approx \frac{\left(S[t]-S_0\right)r S_0{}^{r-1}}{S_0{}^r}\approx  r n[t]
\end{align}

\end{align}

The following attachment is the output after compiling the above code.

Can anyone clarify this on their system. I want to make sure its not my editor bug.

Best,
Abhi

You should always work with the correct placement of the alignment character (»&«) as you do in the first align environment. Sometimes this environment is not enough and you better use the alignat environment.

And as an act of politeness please give some feedback on proposed solutions. The majority of the replies to your former questions yet hasn't got any reaction from your side.
