Do the following before the first class:
  • Complete the Introductory Survey, if you haven't done so already.
  • Install Mathematica on your computer. If you've already installed Mathematica, open it up and check that your license key is still active. You might be prompted to upgrade to the most recent version. For assistance, see this IT Help Desk page.

Do the following before next class:
  • Read the following pages about the Wolfram Language: Fractions & Decimals, Variables & Functions, Lists, Iterators, and Assignments.
  • Modify the code from class to complete the Archimedes's Method practice problems, and upload your solutions to the Archimedes's Method assignment on Moodle.
  • Read pages 13–25 in our Experimental Mathematics text. Come to class prepared to explain what the text means by accuracy, efficiency, and representation.
  • If you're curious why the sum of reciprocals of squares converges to \(\pi^2/6\) (on the Intro Mathematica practice problem), then watch this video.

Inverse tangent formulas for \(\pi\)
Do the following before next class:
  • Complete the Inverse Tangent Formulas practice problems and upload your solutions to the Inverse Tangent Formulas assignment on Moodle.
  • Read Section 1.5 (pages 33–38) in our Experimental Mathematics text. Do Exercise 1.27 (not to turn in). How are the methods in this section different from what we have seen so far?
  • Take a look at the \(\pi\) Project, due next Friday. You don't need to write any code for this yet, but start thinking about the problem and planning the methodology you will use for this project.

Do the following before next class:
  • Finish the Dart Board \(\pi\) practice problems from Wedneseday and upload your solution to the Dart Board Pi assignment on Moodle.
  • Watch The magic of Fibonacci numbers, a 6-minute TED talk by Arthur Benjamin.
  • Read Section 2.2 (pages 51–60) in our Experimental Mathematics text.
  • Recommended: Read Chapter 1, "Flourishing," in Mathematics for Human Flourishing by Francis Su, available here on JSTOR. (If necessary, log into JSTOR using your St. Olaf account.) By next Wednesday, you will answer two reflection questions (see below) based on this text about mathematics as a human activity.
Monday

Fibonacci implementations
Do the following before next class:
  • Read Chapter 1, "Flourishing," in Mathematics for Human Flourishing by Francis Su, available here on JSTOR. (If necessary, log into JSTOR using your St. Olaf account.) Then answer the following questions, writing at least one paragraph per question.
    1. Describe any virtues you have acquired as a result of doing mathematics. (Think of virtues as aspects of character that mathematics might build, such as habits of mind, that shape the way you approach life.)
    2. What value is there in studying math if you'll never use what the math that you're learning?
    The important thing is to be thoughtful about your answers. Submit your answers to the Flourishing assignment on Moodle.
  • Read Section 2.3 up to the "Further Generalizations" heading on page 72 in our Experimental Mathematics text. Focus on the process of discovering Cassini's identity and the methods presented for verifying the identity for lots of indexes \(n\).
  • Complete the Computing Fibonacci practice problems and upload your solutions to the Computing Fibonacci assignment on Moodle.
  • Optionally, begin revising your \(\pi\) Project. Talk with the professor if you have questions about how to do this. Revisions are due Monday, September 29. You may submit your revisions to the same project link on Moodle.

There is no assignment over break. However, you could consider the following:
  • If there is a project from earlier in the semester that you have not turned in yet, you may still use a token to turn it in. Break could be a good time to work on that project.
  • Optionally, work on a challenge problem.
Have a great Thanksgiving break! No class November 26 or 28.
