NOTES:

- Alternate stylesheets are available from: "View -> Use StyleSheet -> TeX | Mathematica"
- Click on a MathML fragment to view its WYSIWYG source.
- In the examples below, the text won't be allowed to decrease pass the scriptminsize or your browser's minimum allowable font size -- this can be set with, e.g, user_pref("font.minimum-size.x-western", 10). To see the effect of the gradual decrease induced by changes in script levels more clearly, you may have to increase your default font size in the menu: "Edit -> Preferences -> Appearance -> Fonts".

- Here is how the alphabet looks like at scriptminsize:
a, b, c ... x, y, z- Here is how greek letters look like at scriptminsize:
α, β, γ ..., ψ, ω, ϑ, ϒ, ϖ- Here is how numbers look like at scriptminsize: 0, 1, 2, ..., 10, 11, 12, ...
- You can use "View -> Text Zoom" in the usual way to zoom the MathML text along with the other text.
- There is a tracker bug where you can report rendering errors on the demos.

MathML has two root objects, an `<msqrt>`

$\sqrt{x}$
and an `<mroot>`

$\sqrt[3]{x}$.
These are pretty simple. About all you can do with them is see how the
rendering stretches them in various ways: horizontally
$\sqrt{{\mathrm{sin}}x{\mathrm{cos}}y}$,
vertically
$\sqrt{\frac{\frac{1}{2}}{\frac{3}{4}}}$
and
$\sqrt{{{\mathrm{det}}\left(\begin{array}{cc}1& 2\\ 3& 4\end{array}\right)}^{2}}$,
as well as
$\sqrt[xyzw]{2}$,
$\sqrt[\frac{\frac{1}{2}}{\frac{3}{4}}]{2}$,
and
$\sqrt[\lceil {det}\left(\begin{array}{cc}1& 2\\ 3& 4\end{array}\right)\rceil ]{2}$.

The formula of Binet shows how the *n*-th term in the Fibonacci series
can be expressed using roots
$${f}_{n}=\frac{1}{\sqrt{5}}\left[{\left(\frac{1+\sqrt{5}}{2}\right)}^{n}-{\left(\frac{1-\sqrt{5}}{2}\right)}^{n}\right]$$
