Mathematics 2243 (Linear Algebra and Differential Equations)



CourseLib Page

Prerequisites: Math 1272, or 1282, or 1372, or 1572.

Required text: Differential Equations and Linear Algebra, 3rd or 4th edition by Edwards and Penney.

Course content: This course consists of two related parts, linear algebra (matrices, determinants, Gaussian elimination, vector spaces, eigenvalues, diagonalization) and ordinary differential equations (linear equations, Wronskian, solution by eigenvalues and eigenvectors). We will cover most of chapters 1, 2, 3, 4, 5, 6, 7 and 10.

Homework: Homework will be assigned in class every day and the assignment will be posted on the course page. Homework will not be collected and graded. Yet doing homework is absolutely indispensable for success in the course. Problems on quizzes and exams will be very similar to the homework problems.

Quizzes: A quiz will be given every Tuesday starting September 12. It will be based on the homework assigned during the preceding week. You cannot make up a quiz. Two lowest quiz scores will be dropped.

Exams: There will be three midterm exams in discussion sections on Thursdays, October 5, November 2 and November 30 and a final exam on Friday, December 15, 12:00 - 03:00pm, room to be announced.

Make up exams: Will be allowed only under truly exceptional circumstances. You must notify the lecturer, not the TA, at least a week in advance.

Calculators: Basic scientific calculators are allowed in exams and quizzes. These are calculators that can evaluate trigonometric, exponential and logarithmic functions. Graphing calculators or calculators that can do symbolic manipulations will not be allowed during exams and quizzes.

Final grade: Quizzes count for 25%, each of the midterm exams for 15% and the final exam for 30%.
