WYSIWYG Equation Editor

1. Equation Editor

Students and teachers of math, engineering, and the physical sciences will love this feature of Namo WebEditor 3.0. Using the integrated Equation Editor, you can edit math formulas right on your web page as easily as editing ordinary text. Equation Editor uses TeX/LaTeX grammar, so it's compatible with all your existing applications. MathML is also supported, so when web browsers begin supporting MathML, Namo WebEditor will be ready.

2. Visual Editing Mode

In Visual editing mode, you input and edit math formulas by click on buttons and selecting from drop-down menus.

3. Script Editing Mode

In Script editing mode, you use standard TeX/LaTeX grammar to enter and edit your formulas.

3. Binomial Expressions

Binomial expressions are operators between two items. For example, + and - are binomial expressions. Binomial expressions have a space before and after them.

\triangleright	\triangleleft	\star	\cdot	\times	\ast
\div	\diamond	\pm	\mp	\oplus	\ominus
\otimes	\oslash	\odot	\bigcirc	\circ	\bullet
\bigtriangleup	\bigtriangledown	\cup	\cap	\uplus	\wedge
\vee	\setminus	\wr	\amalg	\sqcap	\sqcup
\dagger	\ddagger

4. Relational Expressions

Relational expressions have a space before and after them like binomial expressions. Relational expressions can include a slash signifying inequality.

\smile	\frown	\asymp	\equiv	\subseteq	\supseteq
\leq	\geq	\preceq	\succeq	\sim	\approx
\subset	\supset	\ll	\gg	\prec	\succ
\simeq	\propto	\in	\ni	\not	\mapsto
\perp	\vdash	\dashv	\sqsubseteq	\sqsupseteq

5. Arrow Symbols

Arrow symbols are a kind of relational expression and can be used in various ways.

\leftharpoonup	\leftharpoondown	\rightharpoonup	\rightharpoondown	\leftarrow	\rightarrow
\uparrow	\downarrow	\leftrightarrow	\nearrow	\searrow	\Leftarrow
\Rightarrow	\Uparrow	\Downarrow	\Leftrightarrow	\nwarrow	\swarrow
\mid	\parallel	\updownarrow	\Updownarrow

6. Big Operators

\sum	\prod	\coprod	\int	\oint
\bigcap	\bigcup	\bigsqcup	\bigvee	\bigwedge
\bigodot	\bigotimes	\bigoplus	\biguplus

Following are examples of big operators.

7. Parentheses (Delimiters)

You can use the following delimiters in your formulas.

(	)	[	]	\{	\}
\lfloor	\rfloor	\lceil	\rceil	\langle	\rangle
/	\backslash	\\|	\uparrow	\downarrow	\updownarrow
\uparrow	\downarrow	\updownarrow	\|

8. Accents

\hat{a}	\breve{a}	\grave{a}	\bar{a}	\dot{a}
\check{a}	\acute{a}	\tilde{a}	\vec{a}	\ddot{a}

9. Decorations

\overline{abc}	\underline{abc}	\overbrace{abc}	\underbrace{abc}
\widehat{abc}	\widetilde{abc}	\overleftarrow{abc}	\overrightarrow{abc}

10. Spaces

\,	\:	\;	\!	\quad	\qquad
Narrow Space	Medium Space	Big Space	Decrease Space	EM Space	Double EM Space

11. Functions

You can use following functions.

\arccos	\cos	\csc	\exp	\ker	\limsup	\min	\sinh
\arcsin	\cosh	\deg	\gcd	\lg	\ln	\Pr	\sup
\arctan	\cot	\det	\hom	\lim	\log	\sec	\tan
\arg	\coth	\dim	\inf	\liminf	\max	\sin	\tanh

Entering math formulas in Script Mode

1. Fractions (frac)

n_0 + \frac{1}{n_1
      + \frac{1}{n_2
      + \frac{1}{n_3
      + \frac{1}{n_4+\cdots}}}}

2. Square Root (sqrt)

y=\sqrt{x^2+\sqrt{x+12}}

3. Matrices

\left[
\begin{array}{cccc}
\a_{11} & \a_{12} & \cdots & \a_{1n} \\
\vdots & \vdots & \ddots & \vdots \\
\a_{n1} & \a_{n2} & \cdots & \a_{nn} \end{array}
\right]

Equation Editor supports "array" in LaTeX and "matrix, pmatrix, bmatrix and dmatrix" in AmsLaTeX.

4. Eqnarray

\begin{eqnarray}
y & = & x^2 + 1\\
y & > & a - b + c - d + e - f + \\
