• Part 2 (groups) due on the OpenLab Monday, October 23
• Instructions here

Test #2

• Thursday, October 5
• Covers Chapter 3 (Numerical Methods)

Tuesday, September 26 to Monday, October 2

#### 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

• Are you bad at math? Really??? (Instructions here)

#### WeBWork

• Numerical Methods-Euler
• Numerical Methods-Improved Euler
• Numerical Methods-Runge-Kutta
• The Runge-Kutta problem may give you an error message but you should still be able to complete the problem

#### 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
• Test #2
• Thursday, October 5
• Covers Chapter 3 (Numerical Methods)
• Project #1
• Part 1 (partners) due on the OpenLab Monday, October 16
• Part 2 (groups) due on the OpenLab Monday, October 23

## Background

“I’m bad at math.” This is something I’ve heard from a number of students over the years. It’s devastating to me to hear anyone say this about themselves… let alone my own students… in the middle of actually solving a math problem.
