HotEqn is a Java applet to view and display mathematical equations on the Web. The applet uses the familiar LaTeX notation to code its equations. Fontsizes are variable, so the applet can be used to display inline equations as well. The window below shows the output of an applet. |

The
applet scans and parses LaTeX strings. In the example shown above, a LaTeX
string has been given as an applet parameter. After pressing the button "Set",
the string entered in the text area, is interpreted and fonts are
downloaded from the server where the applet is stored on. This may take a
while and is shown by the red hour glass symbol in the center of the
applet window. Load activities and error messages are displayed in the
Navigator's status line.
The applet supports the LaTeX mathematics described in chapter 5 of the books of H. Kopka. With the exception of some seldom used features, the full mathematics style is available. The display of formulas may look slightly different from that of the printed version. In addition to the base language set, some extensions to LaTeX are introduced, which make the display on the screen more comfortable. A short look on the LaTeX features is included in the primer section.
For those who intend to use HotEqn locally or from their home server, the applet should be stored on their sites. The HotEqn applet is freeware and can be downloaded from the download section on the developers edge page. The applet consists of a set of class and font files, which are described on the developers edge page.
