Week 10 checklist

Monday, November 4 to Sunday, November 10

Lesson

  • 4.8 Spanning and Linear Independence in $\mathbb{R}^n$ (continued)

WeBWorK

  • Linear Independence

OpenLab

  • Catch up on any old OpenLab assignments that you’ve missed (you can see old weekly checklists here)
  • Next week’s OpenLab assignment will involve Test #2 solutions (instructions coming soon, will be similar to those for Test #1 solutions)

Other

  • Last day to withdraw from the course: Wednesday, November 6
  • If you would like to estimate grades for upcoming assignments and see how your current grades would translate into an overall course grade, you can play with the spreadsheet here. Start a new row and enter your grades on the left (unshaded) side; don’t touch the right (shaded) side where the overall grades appear.

Week 9 checklist

Monday, October 28 to Sunday, November 3

Lessons

  • 4.6 Parametric Lines (part 2)
  • 4.7 Planes in $\mathbb{R}^3$
  • 4.8 Spanning and Linear Independence in $\mathbb{R}^n$ (part 1)
    • Geogebra: linear combinations and span
      • This shows the example we were discussing at the end of Wednesday’s class:
        • the vectors $\vec{u}_1$ and $\vec{u}_2$ are shown in black and $\vec{v}$ is shown in red,
        • $span\{\vec{u}_1, \vec{u}_2\}$ is the turquoise plane,
        • you can play with the parameters $a$ and $b$ on the left to see different linear combinations of $\vec{u}_1$ and $\vec{u}_2$ in blue; you’ll notice that all the blue vectors will live in the turquoise plane (and so does the red vector $\vec{v}$, since it is a linear combination of $\vec{u}_1$ and $\vec{u}_2$).

WeBWorK

  • Parametric Lines (reopened)
  • Planes in $\mathbb{R}^3$
  • Spanning Sets
    • Notice: some questions have a limited number of attempts

OpenLab


Other

  • Test #2: Monday, November 4
    • 3.1, 3.2, 4.1-4.8 (spanning sets)
  • Last day to withdraw from the course: Wednesday, November 6

Week 8 checklist

Monday, October 21 to Sunday, October 27

Lessons

WeBWorK

  • Projections
  • Cross Product
  • Parametric Lines
    • Even though we did not spent a lot of time on this topic in class, you can still complete all the problems on this WeBWorK set
  • Planes in $\mathbb{R}^3$

OpenLab

  • Reply to any MAT 1375 students’ questions here
  • Are you bad at math??? (Instructions)

Coming up…

  • Test #2: Monday, November 4
  • Last day to officially withdraw from the course: Wednesday, November 6
