Excel ODEs

Use these questions as a learning tool. Treat them like a quiz. Answer in your mind, and using the tool, and writing them down. Make it stick!

• Quiz yourself
• How much can you remember without this list (below)?
• What is missing from this list?
• Don’t just go through the posted notes to answer this. First, recall everything you can, and try it out. Then review notes to recall what you missed.
• Develop the “muscle memory” of using the tool

• What is the form of a general ODE?
• How is the constant of integration handled?
• Derive the formula for the Explicit Euler (EE) method
• How is EE implemented in Excel?
  • How to setup the time grid?
  • How where to put the initial condition?
  • How to “advance” the solution by filling down?
• How are systems of ODEs treated?
  • What is the same?
  • What is different?
