This website is designed to be usable with a wide variety of computing platforms and web browsers. Due to the highly mathematical nature of its content and the large variation in support for standards like XHTML and MathML by today's browsers, this is a complex task. If you have questions or comments regarding the usability or accessibility of this site, please contact our webmaster, Mike Litzkow <mlitzkow@facstaff.wisc.edu>. Questions regarding the content of the site should be directed to your instructors.
This site is best viewed with a browser which supports both XHTML and MathML. Firefox and other "mozilla-based" browsers are in this category. However, you may need to download and install the MathML fonts as these are not part of the default installation. MathML fonts for Firefox and other mozilla-based browsers are available at http://www.mozilla.org/projects/mathml/fonts/.
For those who are unable to use a browser which supports both MathML and XHTML, we have supplied an alternative set of pages which use images of mathematical content instead of MathML. These pages may not look quite as good at the MathML versions, and more importantly, those images will not resize when you use your browser controls to resize the text. However, these pages should be useable from almost any browser. Unfortunately, we have discovered that these pages do not work correctly with Opera. They have been tested successfully with Internet Explorer, Firefox, Safari, and Mozilla.
Every page on this website has two versions. The XHTML + MathML version ends in ".xhtml", and the HTML + images version ends in ".html". If you know the capabilities of your browser, you can use the guidelines above to choose which content to view. Once you go to a ".html" page, every time you follow a link or button to another page, you will get another ".html" page. Similarly, if you go to a ".xhtml" page, every link and button will lead you to another ".xhtml" page. If you are unsure of the capabilities of your browser, we recommend that you try the ".xhtml" version of the content first. If you find that some of the mathematical formulae and expressions don't look right, then switch to the ".html" versions or use a more standards-compliant browser.
