- About this course:

       - extends single variable calculus to higher dimensions;
       - provides vocabulary for understanding the fundamental
         equations of nature (e.g., weather, heat, planetary  motion,
         waves, finance, epidemiology,  quanta, bioinformatics, etc.);
       - provides tools for describing curves, surfaces, and other
         graphical objects in three dimensions;
       - develops methods for solving optimization problems with and
         without constraints;
       - prepares you for further study both in other fields of
         mathematics and its applications;
       - improves thinking skills, problem solving skills,
         visualization skills, and computing skills;
       - taught by trained faculty and teaching fellows in small
         coordinated sections rather than in one big lecture.

           with any academic work, please cite sources consulted.

-  Reading Period: Optional class wide reviews based on practice examinations.
           Complete  either a short project or an hour long section test.


- Grades: There is a total target of T=2000 points for this course.
        Roughly, we expect people who end up with over 1800 points to
        receive some kind of A, people who have 1600-1890 points to 
	receive some kind of B, etc. A maximum of 1620 points can be 
	obtained during the term:

            12 Homeworks, each 60 points               720 points
             2 Hour Exams, each 350 points             700 points
             1 Project or Section Test, 200 points     200 points
             Total                                    1620

  If you earn N points during the term, your final exam will be worth
  a possible T-N points.  For example,

     1) If you enter the final with all 1620 points and get
     50% correct on the final, your course total will be:
     1620 + (2000-1620) * 50/100 = 1810 (probably a low A or high B).

     2) If you enter the final with 860 points and get
     70% correct on the final, your course total will be:
     860 + (2000-860) * 70/100 = 1588 (probably a low B).

   Notice this means you can earn back on the final any point you
   miss during the term, so you always have an incentive to keep
   working.  This grading system is very kind to anyone who
   eventually masters the material by the day of the final, but very
   risky for anyone who tries to wait until then.  Please keep up,
   work lots of problems, go over everything you did not get right
   the first time, ask lots of questions, and you will do fine.
