Category: Weekly checklists (Page 5 of 6)

Tuesday, February 28 to Monday, March 6

Lessons

• 3.1 Euler’s Method
• 3.2 The Improved Euler Method/3.3 The Runge-Kutta Method
• See a comparison of these methods in an example in this spreadsheet

OpenLab

• Project #1 Part 2 (instructions here)
  • If your group doesn’t have a secretary yet, sign up to serve as your group’s secretary here.
  • As a group, you will write a short lesson for the rest of the class.
  • It is up to you to ensure that your group’s secretary has the link to your video so they can include it in the group post.

WeBWork

• Numerical Methods-Euler
• Numerical Methods-Improved Euler

Office hours this week

• Tuesday & Thursday 11:30am to 12:30pm
• Tuesday 2:00pm to 2:30pm
• Thursday 2:00pm to 3:00pm

Coming up

• We start Chapter 5 in Week 6
• Chapter 5 has some similarities with Chapter 2 in that you will be solving differential equations by hand, but in Chapter 5 you will be solving second order equations

Tuesday, February 21 to Monday, February 27

• No class Tuesday, February 21 (follows a Monday schedule)
• Test #1: in class, Thursday, February 23
  • Remember: there will be no make-up tests. If you have to miss this week’s test (for example, if you are sick) you will contact the Center for Student Accessibility who will confirm your excused absence. See our grading policy here.

Extra office hours

• Tuesday, February 21, 11:30am to 12:30pm
• Zoom link
• Notes
• In order to use the time we have efficiently, I recommend coordinating with your classmates (in the Discord or WhatsApp chats) ahead of time to decide which material most of you would like to discuss, which questions most of you have about it, and which problems most of you would like to see me solve.

Project #1 Part 1 due on the OpenLab Monday, February 27

• Instructions here

WeBWorK due Monday, February 27

• Complete ONE of the following sets
  • Applications of First Order Equations-Cooling and Mixing
  • Applications of First Order Equations-Growth and Decay Open
  • Applications of First Order Equations-Elementary Mechanics

Tuesday, February 14 to Monday, February 20

Lessons:

• 2.4 Part II: Nonlinear homogeneous equations
• 2.5 Exact Equations
• Chapter 2 “review”

OpenLab: Due Monday, February 20, 11:59pm

• Black history month profile (instructions here)
• Two Test #1 review assignments (instructions here)

WeBWorK:

• First Order Equations-Nonlinear Homogeneous
• First Order Equations-Exact
  • WeBWorK entry hints:
    • Some WeBWorK questions on these sets require you to treat c as a variable instead of all possible constants. Add c as usual in your integration step, but don’t try to simplify using expressions like 2c=c or -c=c. For example, if you are sure you have the correct answer for First Order Equations-Nonlinear Homogeneous: Problem 4, try changing your +c to a -c. (These are correct, but some WeBWorK questions are not set up to handle them.)
    • Some WeBWorK questions don’t like it if you rewrite fractions with negative signs. For example, if you get a term that looks like $\frac{f(x)}{-g(x)}$ as part of a solution and you simplify it as $-\frac{f(x)}{g(x)}$, try leaving it as $\frac{f(x)}{-g(x)}$.

• Project #1
