Linear Algebra with Applications, 4th Edition
Linear Algebra with Applications, 3rd Edition
Linear Algebra with Applications, 5th Edition
A key matching HW exercises in different editions is available on request.
The older 2nd edition of the text may also be used. The material is fundamentally the same in all editions and all homework assignments will be made available as printable PDFs. Additional supplements on various topics in differential equations will also be made available during the course.
We will meet every Monday, Wednesday, and Friday from 9:30am to 11:30am in Harvard Hall 201.
Classes began Monday, June 19.
Robert Winters' Office Hours: Mondays, Wednesdays, and Fridays immediately following class (if necessary we'll move from Harvard 201 elsewhere to continue the conversation). Other times may be scheduled by appointment, if necessary. My Summer School office is Science Center 308.
TA Jeremy Marcq has scheduled his weekly section each Friday from 12:00pm to 1:00pm at a location to be determined. This day/time is preliminary and may change. Jeremy will communicate this information via email.
HW #1 problems (PDF) - due Fri, June 23. Turn in only those problems designated as such. There are also additional practice problems that you may try at your convenience that are not to be turned in.
HW #2 problems (PDF) - due Wed, June 28. Turn in only those problems designated as such. There are also additional practice problems that you may try at your convenience that are not to be turned in.
Topics to be covered include Gauss-Jordan reduction and systems of linear equations; matrices and linear transformations; linear independence; subspaces; matrices and coordinates relative to different bases; general linear spaces; orthogonality and least-squares approximation; inner product spaces; determinants; eigenvalues, eigenvectors, and the spectral theorem; discrete and continuous dynamical systems; phase-plane analysis of linear and nonlinear systems of ordinary differential equations; and function spaces and differential operators.
This course is primarily a course in Linear Algebra. It has always included applications to Differential Equations (perhaps 15% of the course), but the intention has never been to serve as a substitute for a full course in Differential Equations. This summer we will likely provide more focus on the applications of Linear Algebra to Differential Equations than in summers past.
Text: Linear Algebra With Applications, 4th Edition (2008) or 3rd Edition (2005) by Otto Bretscher, published by Prentice-Hall. The new 5th Edition (2013) of the text may also be used, but HW problems are currently keyed to the 4th Edition. Use the links to the left to find the best online prices for a text (used copies and older editions are considerably less expensive). We will cover almost all topics in this book, and homework will be assigned from its large collection of exercises. The material is fundamentally the same in all editions and all homework assignments will be made available as printable PDFs. A key matching HW exercises in different editions is available on request. Additional supplements on various topics in differential equations will also be made available during the course.

Note: If you must turn in homework assignments outside of class, you can use the Math S-21b Dropbox located on the 2nd floor of the Science Center. As you exit the elevators on the 2nd floor, turn left and take an immediate left down the corridor with wooden mailboxes mounted on the right-hand wall.
