The WebWork assignments in this course are available on the 342 WebWork Page, while the written homework assignments will appear here. Some Tips on Problem Solving are available as suggestions for the written assignments. | |||||
The instructor will write lecture notes for the course (see below) in lieu of an official textbook as the semester progresses. The course will generally follow the presentation in Leon's “Linear Algebra With Applications” (9th edition), but it is not necessary to purchase the textbook for this course. |

How to Get Extra Help | |||
---|---|---|---|
Attend Lecture | Missing lecture is a bad idea! If for any reason you cannot make it to a class, you should review notes from someone who did attend. You are responsible for all material covered in lecture. | ||
Read the Lecture Notes | The lecture notes are intended as review material, although many students like to read them as preparation before attending the lecture on the corresponding topics. Please note that the electronic notes will not always be identical to the material covered in class: this is by design, so as to provide you a slightly different perspective on the material. | ||
Ask Questions Via WebWork | On each WebWork problem's page, there is an "Email Instructor" button at the bottom. If you are having difficulty with a problem (if you are stuck or you believe there is an error or issue with the problem) you can ask a question at any time, and the TA or instructor will typically respond within 24 hours, if not sooner. | ||
Attend Office Hours | Office hours are specifically reserved for you to receive individual, one-on-one help from the instructor. Office hours will be the most effective when you have already put in effort to learn the material on your own (including trying to solve the homework problems), and when you come in with a list of specific questions or topics you are struggling with. | ||
Tutoring | The university offers a wide variety of free tutoring services both online and in-person. Please consult the ASU Tutor Search page for additional information. It is also possible to hire private tutors, some of whom are listed here. | ||
Math Community Center | The Math Community Center is located in Wexler 303 and staffed by faculty and graduate students Mon-Fri, typically 10:30am-6pm. It is a common location intended for students to collaborate and have peer mentoring sessions, and also provides structured course assistance from graduate-student tutors. |
