Homework: Homework will be given out at least a week in advance and is due Mondays, 12pm (Noon) in the appropriate box outside room 253 Sloan. In case Monday is a holiday, homework is due the following Tuesday at 9am. It is also posted on the web. Solutions are discussed in the sections Thursday, and will be posted on the web Thursday.
Grading: Both exams and the homework will contribute toward the final grade. The midterm and the final are 3hour take home exams that will be given out in class. Collaboration:
Collaboration is allowed on the homework, but your writeup
must be in your own words and may not be copied.
Collaboration is not allowed on the exams. You may use books
and notes while working on the homework, but you may not
consult homework sets or solutions from previous years of
Math 2a Practical. Recitations: Go to the recitations! Each week, a portion of the recitation will be dedicated to introducing some computational (or even theoretical) aspect which the Instructor will not have time to present in class. In general, get to know your TA and bug him/her to death (figuratively speaking) with your questions, and try to fill in all the holes in your understanding of the subject. 
Elementary Differential Equations with Boundary Value Problems, 8th edition, by W.E. Boyce, R.C. diPrima, Wiley & Sons. 0471433381
We shall treat most topics covered in the textbook. However, certain topics might be treated differently in class than they are in the book, and it is the material from class that you are assumed to know for the midterm and final.
