Equation numbering

The templates {{NumBlk}} and {{EquationRef}} can be used to number equations. The template {{EquationNote}} can be used to refer to a numbered equation from surrounding text. For example, the following syntax:

{{NumBlk|:|<math forcemathmode='native'>x^2 + y^2 + z^2 = 1 \,</math>|{{EquationRef|1}}}}

produces the following result (note the equation number in the right margin):

$x^2+y^2+z^2=1$		(Vorlage:EquationRef)

Later on, the text can refer to this equation by its number using syntax like this:

As seen in equation ({{EquationNote|1}}), blah blah blah...

The result looks like this:

As seen in equation (Vorlage:EquationNote), blah blah blah...

Note that the equation number produced by {{EquationNote}} is a link that the user can click to go immediately to the cited equation.

Color

Equations can use color:

• {\color{Blue}x^2}+{\color{YellowOrange}2x}-{\color{OliveGreen}1}

  $x^2+2x-1$

• x_{1,2}=\frac{-b\pm\sqrt{\color{Red}b^2-4ac}}{2a}

  $x_{1,2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

Some color names are predeclared according to the following table, you can use them directly for the rendering of formulas or for declaring the intended color of the page background.

$0+1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+\cdots$

This can be remedied by putting a pair of braces { } around the whole expression:

{0+1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+\cdots}

Alignment with normal text flow

Due to the default CSS

img.tex { vertical-align: middle; }

an inline expression like $\underset{-N}{\overset{N}{\int }}{e}^{x}dx$ should look good.

If you need to align it otherwise, use style="vertical-align:-100%;">... and play with the vertical-align argument until you get it right; however, how it looks may depend on the browser and the browser settings.

Also note that if you rely on this workaround, if/when the rendering on the server gets fixed in future releases, as a result of this extra manual offset your formulae will suddenly be aligned incorrectly. So use it sparingly, if at all.

Centering

We introduce the new attribute display with the two options "inline" and "block".

Inline

If the the value of the display attribute is inline the render will render math in inline mode, i.e. there will be no new paragraph for the equation and the operators will be rendered consuming only little vertical space.

Example

The sum ${\sum }_{i=0}^{\mathrm{\infty }}{2}^{-i}$ converges to 2.

The next line-width is not disturbed by large operators.

The code for the math example reads:

<math forcemathmode='native' display="inline">\sum_{i=0}^\infty 2^{-i}</math>

Technical implementation

Technically it will add the command \textstyle will be added to the user input before the tex command is passed to the renderer. The result will be displayed without further by outputting the image or MathMLelement to the page.

Remark

The convention https://en.wikipedia.org/wiki/Wikipedia:Manual_of_Style_(mathematics)#Using_HTML is really annoying. I'd prefer to use inline math for that, since it helps to differentiate between math and other elements.

Block

In block-style the equation is rendered in its own paragraph and the operator are rendered consuming less horizontal space.

Example

The equation $$\text{geometric series:}\begin{array}{r}\sum _{i=0}^{\mathrm{\infty }}{2}^{-i}=2\end{array}$$ is used in a joke about mathematicians entering a bar and ordering beer.

It was entered as

<math forcemathmode='native' display="block">\text{geometric series:}\quad \sum_{i=0}^\infty 2^{-i}=2 </math>

Technical implementation

Technically it will add the command \displaystyle will be added to the user input, if the user input does not contain the string \displaystyle or \align before the tex command is passed to the renderer. The result will be displayed in a new paragraph. Therefore the style of the MathImage is altered i.e. the style attribute "display:block;margin:auto" is added. For MathML it is ensured that display=inline is replaced by display block which produces a new paragraph

Discussion

Fréderic Wang would prefer that displaystyle is always added in depended of the fact if \displaystlye is already in the equation. He remarks that it has to be checked if that works if the equation starts with \begin.

Not specified

If nothing is specified the current behavior is preserved. That means all equation are rendered in display style but not using a new paragraph.

Example

The sum $\sum _{i=0}^{\mathrm{\infty }}{2}^{-i}$ converges to 2.

The next line-width is disturbed by large operators.

The code for the math example reads:

<math forcemathmode='native'>\sum_{i=0}^\infty 2^{-i}</math>

The equation

$\text{geometric series:}\sum _{i=0}^{\mathrm{\infty }}{2}^{-i}=2$

is used in a joke about mathematicians entering a bar and ordering beer.

It was entered as

<math forcemathmode='native'>\text{geometric series:}\quad \sum_{i=0}^\infty 2^{-i}=2 </math>
