Students should know that the software packages Maple, Mathematica, and Scientific Notebook, Word, or Workplace are useful tools for this and all other science and engineering classes. All these packages are available for student use at reasonable costs.
Especially note that Scientific Notebook is available in both a 30-day free trial version, and a free viewer version. I encourage you to download the viewer and use it. Some of the notes given in this course (those in LaTex) are best read by using the Scientific Notebook viewer.
You should also download the free Adobe Acrobat Reader. Acrobat is sometimes useful to view the notes (those in PDF).
