Note that while collaborating on homework and lab assignments is encouraged, it is not acceptable to simply copy another person's work.

Textbook:
Differential Equations and Linear Algebra, 2nd or 3rd Edition, Edwards and Penney, Prentice-Hall, is our primary textbook. It does not matter which edition of the text you have.

Topics:
This course will build on your knowledge of calculus, extending it to differential equations. In addition to their intrinsic mathematical interest, differential equations are applied in a wide variety of fields. In order to understand systems of linear differential equations, we will also learn some basic linear algebra. We will try to cover some sections from every chapter of the book, although more attention will be given to chapters 1 through 7. These will be covered at a pace of roughly one chapter per week.

Tentative topic outline (subject to revision):
Week 1: Aug.29 - Sep.2 Introduction, slope fields and separable ODES Ch 1.1 - 1.3
Week 2: Sep.5 - Sep.9 1st order ODEs and numerical methods Ch 1.4-1.6, 2.4-2.6
Week 3: Sep.12 - Sep.16 Autonomous ODEs, 1D equilibria, matrix introduction Ch 2.1 - 2.4, 3.1-3.3
Week 4: Sep.19 - Sep.23 Matrix Algebra: row reduction, inversion 3.1 - 3.5
Week 5: Sep.26 - Sep.30 Determinants, Vector Spaces 3.6 - 4.1
Week 6: Oct.3 - Oct.7 Vector Spaces: bases, linear independence, subspaces, spans 4.1 - 4.6
Week 7: Oct.10 - Oct.14 2nd order ODEs and review 5.1 - 5.2
Week 8: Oct.17 - Oct.21 Higher order ODEs, numerics 5.3 - 5.6
Week 9: Oct.24 - Oct.28 Eigenvectors and eigenvalues 6.1 - 6.3
Week 10:Oct.31 - Nov.4 Systems of differential equations 7.1 - 7.5
Week 11:Nov.7 - Nov.11 Review
Week 13:Nov.14 - Nov.18 Laplace Transform 10.1 - 10.5
Week 14:Nov.21 - Dec.2 Nonlinear Systems 9.1 - 9.4
Week 15:Dec.5 - Dec.9 Review

Exams:
There will be two midterms (tentatively October 14th and November 11th) and a final exam (8-10 am Friday December 16th for section 9/10 (noon section) and 2-4 pm Tuesday December 13th for section 13/14 (2 pm section)). A calculator and sheet of notes is allowed on each exam. For the final you can use two pages of notes.

Practice exams:
Practice tests for the midterms and final will be posted here 1 week before the relevant exam.

Calculator Policy:
Calculators are allowed during exams (note: an internet-capable device is not considered a calculator). However, you are expected to show the steps that justify your answers, and to give exact answers whenever possible. This also applies to homework unless the question specifically instructs you to use a computer or calculator. On a test, any step on which you use a calculator must be clearly indicated (just write "CALCULATOR" or "CALC").

Grading:
Grades will be based on your understanding of the material as demonstrated by class participation (mainly worksheets), office hours, homework, labs, and exams. The homework assignments will be weighted equally, with the lowest score dropped. The lowest lab score will also be dropped. The lowest three worksheet scores will be dropped. The approximate weighting is homework is 20%, each midterm 15%, labs 10%, worksheets 15%, and the final exam is 25%. Note that I do not use traditional grading percentages, although generally a score of around 90% of the total is sufficent for an A.

Labs:

We will use the computer algebra system Sage for our labs. Sage can be accessed through a browser at http://sage.d.umn.edu:8008/ or Server 2.

Sage can also be used on a "cloud" version: https://cloud.sagemath.com., although you will have to upload the labs.

Accessing the sage.d.umn.edu server can be done from off-campus if you install the university's VPN connection software.
It may be helpful to read this introduction, written by professor Gregory Bard of UW Stout.

Interactive introduction to Python. This might be easier to use than the CodeAcademy site.
MIT ODE lectures online. This course is somewhat different from ours but there is significant overlap.
Code Academy's brief intro to Python. Totally optional but recommended.
