Final                =   30%

IODE (for "Illinois" and "ODEs"; rhymes with diode) is an educational software package specifically designed for Math 285.
It can be used to explore

• direction fields,
• phase planes,
• mechanical vibrations,
• Fourier series, and
• heat and wave equations.

Prentice Hall has a useful website for the Edwards and Penney textbook.  Look here for an ODE solver, worksheets, animated demonstrations

Short (approximately 10 minutes) quizzes will be given in class roughly every second week. These will cover only the work of the preceding two weeks. In addition here will be two in-class midterms and a final exam. Dates and syllabi will be announced at least one week in advance.  The (tentative) dates for the midterms are Thursday February 26 and Thursday April 15.
