Syllabus

We will cover most of the text. Key topics will include:

Vector spaces, matrices, and linear transformations. Solutions of systems of linear equations. Eigenvalues, eigenvectors, and diagonalization of matrices. Applications to differential equations.

Grading: The grading scheme will be:

Homework 15%Quizzes 5%First Midterm Exam 20%Second Midterm Exam 20%Final Exam 40% .

Your 2 lowest homework scores will not count toward your grade.

Homework: Your assignments will be posted above. They will be collected, in lecture on Mondays, and returned in section. Late homework will not be accepted. However, the lowest two scores will not count toward your grade. You are encouraged to discuss homework problems with one another. However, each of you must write up your solutions independently, in your own words, without supervision or well-meaning influence from anyone else. Disputes regarding homework grading should be discussed with your TA.

Quizzes: Two quizzes will be administered in section. The 1st roughly midway between the beginning of the semester and the first midterm, the 2nd roughly midway between the 2nd midterm and the final. There will be no makeup quizzes. If you miss a quiz then you will get a zero for that quiz. In exceptional circumstances documented by a letter from your doctor or your academic supervisor, the remaining quiz may be given correspondingly more weight to take up the slack.

Midterm Exams will be in class on Mon 4 March and Mon 8 April. Books, notes, phones & calculators are forbidden. You must bring your ID to the exam, and may be called upon to show it. If you do not have your ID and your TA cannot attest to your identity then you may not receive a grade for the exam. The first midterm is scheduled so that the grades will be available before the add/drop deadline. You have the one hour of section time to bring up grading errors or omissions on the midterms, once they have been returned to you. You may not take the exam home and bring it back for corrections.

The Final Exam will be 9am–12pm on Weds 8 May. Further particulars nearer the time.

Absence: You are expected to attend class and take exams as scheduled. There will be no makeup exams. If you miss a midterm exam then you will get a zero for that exam. If you miss the final exam then you will automatically fail the course. In exceptional circumstances documented by a letter from your doctor or your academic supervisor, the remaining homework and final exam may be given correspondingly more weight to take up the slack.

$$ \begin{bmatrix} \sqrt{11} & 1 & 0 & \sqrt{19} \\ 1 & \sqrt{2} & \sqrt{7} & 1 \\ 0 & \sqrt{3} & \sqrt{5} & 0 \\ \sqrt{13} & 0 & 1 & \sqrt{17} \end{bmatrix} \cdot X = 0 $$

Disability: Any student with a disability who may need accommodations in this class must obtain an accommodation letter from Student Disability Services, 385 Garland, (410) 516-4720, studentdisabilityservices@jhu.edu.

Ethics: Don’t get it WRONG, like Kant! Seriously though, cheating & other forms of academic dishonesty are corrosive & harmful to our university:

The strength of the university depends on academic and personal integrity. In this course, you must be honest and truthful. Ethical violations include cheating on exams, plagiarism, reuse of assignments, improper use of the Internet and electronic devices, unauthorized collaboration, alteration of graded assignments, forgery and falsification, lying, facilitating academic dishonesty, and unfair competition.

Report any violations you witness to the instructor. You may consult the associate dean of student affairs and/or the chairman of the Ethics Board beforehand. See the guide on “Academic Ethics for Undergraduates” and the Ethics Board Web site for more information.
