====== Use mathjax for TeX math expressions ======

===== Inline Math =====

If you want to write Tex math expressions on the same line you can use:

  * Dollar signs

  $a^2 + b^2 = c^2$
  
Eg: 

  Expressions like $a^2 + b^2 = c^2$ on the same line

Expressions like $a^2 + b^2 = c^2$ on the same line

  * Escaped parentheses

  \(1+2+\dots+n=\frac{n(n+1)}{2}\)

Eg: 

  Or expressions like \(1+2+\dots+n=\frac{n(n+1)}{2}\)

Or expressions like \(1+2+\dots+n=\frac{n(n+1)}{2}\)


===== Display Math =====

If you want to write TeX math expressions on its own line use:

  * Double dollar signs

  $$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$

Eg: 

  Expressions like $$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$

Expressions like $$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$

  * Escaped square brackets

  \[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]

Eg:

  Or like \[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]

Or like \[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]

===== Math Environments =====

Also, you can use a wide range of TeX math enviroments like: align, align*, alignat, alignat*, displaymath, eqnarray, eqnarray*, equation, equation*, flalign, flalign*, gather, gather*, math, multline, multline*

Eg:

  \begin{align*}
  e^x & = 1 + x + \frac{x^2}{2} + \frac{x^3}{6} + \cdots \\
      & = \sum_{n\geq 0} \frac{x^n}{n!}
  \end{align*}

\begin{align*}
e^x & = 1 + x + \frac{x^2}{2} + \frac{x^3}{6} + \cdots \\
    & = \sum_{n\geq 0} \frac{x^n}{n!}
\end{align*}

**Note:** math environments //should not// be inside the dollar sign delimiters; the environments should stand on their own with just the //\begin// and //\end// statements in order to be parsed correctly.
