Getting Help

Getting good help can sometimes be frustrating. I am trying to make my self available by choosing varied office hours and being available by email. My email response time varies a lot so asking questions early is your best strategy. Sometimes you may have a complex question that would benefit by including a picture in email. This is fine, but please use reduced-size photos -- typically a 250kB picture is sufficient, while a 5MB picture can really bog down email.

In-Class Activities

Assignments

Here are some sample exercise solutions from chapters 6 and 7. Keep in mind that lengthy answers are not necessarily better answers. Consider the brevity of my solutions and their focus on the current linear algebra concepts. And here are two more example proofs. And, here are two examples of how to show if a transformation is linear or not.

(Optional) Midterm #1A Exam Details

Date: Friday October 12
Time: In-Class, 12:10-1:00
Material: Chapters 1-12.
Info: Closed-Book, Closed-Notes. You are expected to know relevant defintions and essential results of theorems. Emphasis will be on conceptual understanding, some mechanics, and ability to construct a clear, accurate and concise proof. This Midterm Exam is optional, and is being provided as an opportunity to improve your Midterm #1 score. If your score on Midterm #1A is better than your score on Midterm #1, then your Midterm #1 score will be replaced by the average of your scores on Midterm #1A and Midterm #1.

If you choose to take this optional Midterm Exam, you must confirm by email to me before noon on Tuesday, October 9. If you do not confirm on time, you cannot take the exam. In consideration of my time and planning, please confirm only if you fully expect to take the exam.

Final Exam Details

I will supply these materials for you to use during the exam. It is simply a copy of most of the definitions, lemmas, theorems and corollaries from the textbook. Date: Friday, December 14.
Time: 1:00-3:00 pm

Skills for the final exam:
  • Demonstrate correct use of linear algebra and mathematical language.
  • Justify linear algebra steps taken to demonstrate/determine/prove/compute.
  • Demonstrate writing a sound formal proof.
  • Determine whether or not a subset of a vector space is a subspace.
  • Understand when a transformation (and matrix) is diagonalizable, and be able to find a diagonalization.
  • Understand when a transfomration (and matrix) is invertible, and be able to find the inverse.
  • Find a basis for a subspace (e.g. range or null space, and other subspaces) and be able to transform vectors (and transforamtion matrices) into the coordinate representation relative to your basis.
  • Use inner product spaces to answer questions about comparing vectors.
  • Understand and implement the Gram Schmidt Method.
  • Understand concepts of pseudo-inverse transformations.
  • Understand and verify properties of projections.
  • Understand and verify properties of symmetric matrices and orthogonal matrices.
