### Learning Resources

• Since it will arrive to Bookstore only next week, we were allowed by the publisher to place Chapter 2 on our website. Please, download it.
• Chapter 1 and preceding material are available for free preview at Amazon.

• Student Solutions Manual: Student Solutions Manual to accompany Boyce Elementary Differential Equations 10th Edition and Elementary Differential Equations w/ Boundary Value Problems 8th Edition—also new edition (optional).

• This class in the previous years

 2012 Spring: 2012 Fall: 2011 Spring: 2010 Spring:
• Online plotters (usually you need to have Java enabled)

Informations about tests and all the announcements could be accessed through the Forum Announcements board.

### Coverage

Note: Chapters 5 and 6 will be covered (if at all) at the very end of the course.

### Tests and Marking Scheme

#### Tests

(all sections)
• Test 1 February 13 (Wednesday), 20:30—21:15, EX 200
• MidTerm March 6 (Wednesday), 20:00—21:30, EX 200
• Test 2 March 27 (Wednesday), 20:30—21:15, EX 200

#### Quizzes

There also will be 4—5 short quizzes from the list of Assigned Exercises. Quizzes will be given without advance warning: Surprise, surprise, we have quiz today! Quizzes include only problems from the assignments.

#### Missing work

There will be no make up (even) for a legitimately missing work, but the remainder will count heavier. Loss of work must be reported the day of the distribution of the respective work.

#### Final mark

(Only for those who legitimately missed less than 50% of the term marks; term grade will not be assigned to other students)

Your Term and Final grades will be computed as follows: \begin{gather} FG= 0.6 \cdot \max\{TG ; FE \} + 0.4 \cdot \min\{TG ; FE\} \tag{Final Grade}\qquad\qquad\\[3pt] TG=\min \{0.4 \cdot MT + 0.2 \cdot T_1 + 0.2 \cdot T_2 + 0.2\cdot Q +B ; 100\}\qquad\qquad \tag{Term Grade} \end{gather} where $TG$, $MT$ and $FE$ are your Term Grade, Midterm and the Final exams marks, $T_1$ and $T_2$ are your preparatory tests marks, $Q$ is the total of your quiz marks, and $B=\min\{B_{\text{class}}+B_{\text{web}},6\}$, where $B_{\text{class}}=0, \ldots, 4$ and $B_{\text{web}}=0 , \ldots , 4$ are the bonus points for the activity in the class and, respectively, contributions to the forum, assigned by instructors.
