Homework Assigments



Week of January 6 - 10, 2025
Assignments Made on:
Monday:
  • Homework 0 As soon as possible, complete the survey questions on Homework 0 (available on our canvas page) and upload them to gradescope. This will let me learn something about you, and will allow you to be familiar with gradescope so that there are no issues with turning in your first assignment.
  • Study: Read section 1.1 and start section 1.2
  • Do: In section 1.1, do 2a and 3a. (The answers are in the back of the book.) Also try 7. Note that a parallelogram is determined by two vectors $\mathbf x$ and $\mathbf y$ as in Figure 1.1 in the text. Then the midpoint of one diagonal is $\frac12(\mathbf x+\mathbf y)$. Write the midpoint of the other diagonal in terms of $\mathbf x$ and $\mathbf y$ and show that they are the same vector.
Wednesday:
  • Study: Read sections 1.2 and start section 1.3 of the text. Having a look at Appendices A and B would be helpful. Also Appendix C on fields might help . But we are going to settle down and concentrate on the fields like the rationals, the reals, or later the complex numbers. In fact, unless explicitly stated otherwise, from this point on, you can assume that our vector spaces are over either the reals or the complex numbers.
  • Do: In Section 1.2: 15, 16, and 18.
Friday:
  • Study: Read Section 1.3
  • Do: In Section 1.3: 3, 19, 23, 28 (Hint: consider #5), and 30.
