### Browser Support for MathML

The XHTML files produced by MathCast are compatible with Mozilla, Firefox, and Netscape browsers, which have internal support for MathML.
Internet Explorer, on the other hand, requires a program update to enable displaying MathML. One such application is Design Science's MathPlayer, available at http://www.dessci.com/en/products/mathplayer. If you want to view MathCast's equation lists in Internet Explorer:

1. Make sure you save your files with the hexadecimal XML layout. This option can be set in the Settings Screen.
2. Edit the XHTML file with WordPad and replace the
   `<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN'`
   `'http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd'`
   `[<!ENTITY mathml 'http://www.w3.org/1998/Math/MathML'>]>`
   with
   `<?xml-stylesheet type="text/xsl" href="http://www.w3.org/Math/XSL/pmathml.xsl"?>`
   You can download pmathml.xsl and place it in the same folder as your XHTML file. In that case, just write
   `<?xml-stylesheet type="text/xsl" href="pmathml.xsl"?>`
