# amp-mathml

#### Description

Displays a MathML formula.

#### Required Scripts

`<script async custom-element="amp-mathml" src="https://cdn.ampproject.org/v0/amp-mathml-0.1.js"></script>`

#### Supported Layouts

## Behavior

This extension creates an iframe and renders a MathML formula.

#### Example: The Quadratic Formula

<amp-mathml layout="container" data-formula="\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]" > </amp-mathml>

#### Example: Cauchy's Integral Formula

<amp-mathml layout="container" data-formula="\[f(a) = \frac{1}{2\pi i} \oint\frac{f(z)}{z-a}dz\]" > </amp-mathml>

#### Example: Double angle formula for Cosines

<amp-mathml layout="container" data-formula="$$ \cos(θ+φ)=\cos(θ)\cos(φ)−\sin(θ)\sin(φ) $$" > </amp-mathml>

#### Example: Inline formula

This is an example of a formula of `<amp-mathml layout="container" inline data-formula="`x`"></amp-mathml>`

, `<amp-mathml layout="container" inline data-formula="\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)"></amp-mathml>`

placed inline in the middle of a block of text. `<amp-mathml layout="container" inline data-formula="\( \cos(θ+φ) \)"></amp-mathml>`

This shows how the formula will fit inside a block of text and can be styled with CSS.

## Attributes

##### data-formula (required)

Specifies the formula to render.

##### inline (optional)

If specified, the component renders inline (`inline-block`

in CSS).
