About the File Formats

The posted assignment solutions, exam solutions, and lecture notes on this web site generally come in 4 different formats:

html:
This stands for "Hypertext Markup Language". These files end in ".html", and need to be read in a Web Browser. If you're reading this, then you're probably using a Web Browser, because this is an html file called "aboutformat.html".

gif:
This stands for "Graphics Interchange Format". The files end in ".gif", and can be read in almost any Web Browser (with the exception of Lynx, which is text-only). Any hand-written notes and solutions, which I scan into the computer using a scanner, are saved in this format.

pdf:
This stands for "Portable Document Format". These files end in ".pdf" and can be viewed by Adobe's Acrobat Reader. This popular software supports graphics, and any detail can be scaled by clicking on a magnifying glass in the toolbar. Adobe Acrobat Reader is free, and can be downloaded from their web site. There is also a web browser plug-in which allows your web browser to read pdf files directly.

mws:
This stands for "Maple Worksheet". These files end in ".mws" and can be used with Maple. Your web browser probably won't know what these files are, so be sure to save them as type "TEXT" when downloading them. You can then use Maple to read them and manipulate them. Maple is not free. However, there is a Student Version available at the SFU Microcomputer Store for a reasonable price. SFU also has a campus-wide all-platform site-license for the full version of Maple on campus computers.
