This is a preview for the new MathML rendering mode (with SVG fallback), which is availble in production for registered users.

If you would like use the MathML rendering mode, you need a wikipedia user account that can be registered here [[1]]

Only registered users will be able to execute this rendering mode.
Note: you need not enter a email address (nor any other private information). Please do not use a password that you use elsewhere.

Registered users will be able to choose between the following three rendering modes:

MathML

E=mc^{2}

Follow this link to change your Math rendering settings. You can also add a Custom CSS to force the MathML/SVG rendering or select different font families. See these examples.

Demos

- From our testing, ChromeVox and JAWS are not able to read the formulas generated by the MathML mode.

-In [[mathematics]], a '''coframe''' or '''coframe field''' on a [[smooth manifold]] <math>M</math> is a system of [[one-form]]s or [[covector]]s which form a [[vector space|basis]] of the [[cotangent bundle]] at every point.  In the [[exterior algebra]] of <math>M</math>, one has a natural map from <math>v_k:\bigoplus^kT^*M\to\bigwedge^kT^*M</math>, given by <math>v_k:(\rho_1,\ldots,\rho_k)\mapsto \rho_1\wedge\ldots\wedge\rho_k</math>.  If <math>M</math> is <math>n</math> dimensional a coframe is given by a section <math>\sigma</math> of <math>\bigoplus^nT^*M</math> such that <math>v_n\circ\sigma\neq 0</math>.  The inverse image under <math>v_n</math> of the complement of the zero section of <math>\bigwedge^nT^*M</math> forms a <math>GL(n)</math> [[principal bundle]] over <math>M</math>, which is called the [[frame bundle|coframe bundle]].
