- Prime proof in Prime_Proof_handout.pdf pdf and Prime_Proof_handout.tex tex
Lesson 2.4, Putting a Fraction into Lowest Terms
Lesson 2.4b, Plotting Functions, Divisibility by 2, 3, 5, 7,
- HW 2.4b supplement: Plotting Functions with Python and zoom office hour sessions one and two on problems with the homework.
- Khan Academy on divisibility by three, and a better, written, exposition.
- I've written up a handout of some Python code for testing divisibility by 2,3,5, and 7. Its purpose is to illustrate how one has to write up instructions for a computer carefully and clearly.
Lesson 2.5, Multiplying Fractions
Lesson 2.7, Dividing Fractions
Lesson 2.8a, More Multiplication
- The "All Odd Numbers Are Prime" joke and joke script. The video of part 1 (explanation of primes) and part 2 (explanation of people) and part 3 (the joke itself) and part 4 (Polya Conjecture)of the odd number joke. The Python code by Professor Connell to test the Polya Conjecture.
Lesson 2.8b, Emails, Prime Numbers
- Prime_Proof_handout.pdf Handout on Euclid's proof, ] and "Euclid's Proof of the Infinitude of Primes" and five-minute video of Mr. Rasmusen going through the proof.
- Handout on writing emails
- Gordon Klein video from Fox's Tucker Carlson Show.
