REC # RECITATIONS
1

Math Topics: Strategies for becoming unstuck when proving something.

Writing Topics: The role of proof, norms of proof writing, proof generation strategies.

Description: For the statements in Homework 1 Problem 1, practice choosing a proof strategy and generating a proof. Recitation begins with a summary of the role of proof in the doing of mathematics, illustrated by the Mathematics Reasoning Diagram (PDF).

2

Math Topics: Probability: Independence & Multiplication

Writing Topics: Precision, Rigor, & Formality

Description: Discuss the proof in the pre‐recitation assignment and how it breaks down, with emphasis on the importance of independence and how the proof obscures whether the events are independent. Practice with additional wrong proofs (PDF).

Math Topics: Probabalistic method and Chernoff bound

Writing Topics: Meaning guiding text, global Known-to-New structure, and revising for economy

Description: Learn to write text that meaningfully guides readers through logic, while helping them to see connections across the text; and learn to revise drafts for economy. Practice on the proof assigned for the homework.

Math Topics: Chernoff bound

Writing Topics: Drawing the logic of a proof to better understand it at a detail level; drafting guiding text to better understand the proof at a higher level, choosing how to order logic when writing up a proof.

Description: After identifying points of confusion in the pre-recitation assignment lecture notes, draw the logic of the Chernoff bound proof, labeling the arrows with guiding text explaining the logic, including at the identified points of confusion. Discuss how the structure of the drawing relates to the structure of the written proof.

Math Topics: Linear Programming

Writing Topics: Drawing to learn

Description: Prove that the given linear program yields the shortest bath between two nodes of a graph, and draw a figure to understand why. Write the dual linear program and prove that it too finds the shortest path. 

Pre-Recitation Assignment

Before recitation, go over Section 4 (Dual) of the notes and observe the figure on page 6, which represents a dual solution to a maximum flow problem. Briefly, answer the following questions:

- What is the purpose of the figure?

- Why is this figure useful? What content does it convey effectively?

- How could the figure be improved? What content does it fail to represent?

Math Topics: Huffman Coding

Writing Topics: Figure Design and Creation

Description: Learn when figures are useful and visual design choices for crafting effective figures. These choices depend on the purpose of the figure. Practice by designing a figure to communicate Huffman Coding, and a proof of the Kraft Inequality. Learn tools for creating figures and how to integrate figures with text.
