Computing the digits of \(\pi\)
Do the following before the next class:
- Watch this video, which explains why the sum of reciprocals of squares converges to \(\pi^2/6\).
- Start the \(\pi\) Project (due
MondayWednesday). Implement at least one of the methods for approximating digits of \(\pi\) before Friday's class. Also look over the sample project report. - Complete Mathematica Quiz 1 (on Moodle).
- Optional bonus: Watch this video to learn why the product formula from the Intro Mathematica assignment converges to \(\pi\).

Computing the digits of \(\pi\)
Do the following before the next class:
- Read How to Create Lists and How to Get Elements of Lists from the Wolfram language documentation.
- Work on the \(\pi\) Project. It's now due Wednesday, but try to make as much progress as you can this weekend, and ask questions on Monday. Prepare a Mathematica notebook that contains your code and discussion. Pay attention to the grading rubric in the assignment file and refer to the sample project report.
- Watch The magic of Fibonacci numbers, a 6-minute TED talk by Arthur Benjamin.
Do the following before the next class:
- Finish the \(\pi\) Project. Pay attention to the grading rubric in the assignment file and refer to the sample project report. Submit your notebook to the Pi Project on Moodle.
- Investigate \( F_n^2 - F_{n+1}F_{n-1} \), where \( F_n \) is the \(n\)th Fibonacci number. Evaluate this quantity for lots of values of \(n\). What pattern do you observe?

Fibonacci identities
Do the following before the next class:
- Catalan's identity says \(F_n^2 - F_{n+r}F_{n-r} = (-1)^{n-r}F_r^2 \). Verify this for at least three values of \(r > 2 \). For each value of \( r \), check at least 100 values of \( n \).
- Vajda's identity says \(F_{n+i}F_{n+j} - F_nF_{n+i+j} = (-1)^n F_i F_j \). Verify this for at least six pairs \(i,j\). For each pair \(i,j\), check at least 100 values of \(n\).
- Submit a Mathematica notebook containing your verifications of Catalan's and Vajda's identities to the Fibonacci Assignment on Moodle. Please put your name at the top of your notebook. (Note that this is an Assignment, not a Project.)

Pell numbers
Do the following before the next class:
- Complete Mathematica Quiz 2 (on Moodle). This quiz covers lists, indexed variables, functions, and Modules.
- Take a look at this paper, which proves various identities involving the Pell numbers. Read through the Introduction, which gives some background about the Pell numbers. Note that Proposition 1 corresponds to our observations in class. Take a quick look at the other propositions and theorems that the authors prove.
- Begin the Pell Project, due Wednesday, March 3.
Do the following before the next class:
- Finish the Pell Project (due Wednesday). Upload your notebook to Moodle.
- Continue your investigation of sequences that arise when iterating the Collatz function or some other function. Bring observations and questions to class on Wednesday.
Extra credit opportunity: Attend either of Dr. Trachette Jackson's lectures on March 2 or 3 and answer these two questions on Moodle to earn two extra-credit points.
