Mastering CS 6120A: Discrete Mathematics and Proof for Computer Science

Claim: ∀n ∈ ℕ, n ≥ 1 → P(n)
Proof (by simple induction on n):
Base case n = 1: …
Inductive hypothesis: Assume P(k) for some arbitrary k ≥ 1.
Inductive step: Show P(k+1) using the hypothesis.

• Example fix: Among 13 people, at least two share a birth month.

He gestured to the crashed system on the screen. "This is a class on Proof. The purpose of mathematics in computer science is to guarantee safety. I created a trap for those who look for shortcuts. The 'fix' you applied creates a buffer overflow in the compiled executable. It makes the proof look correct to a lazy eye, but it renders the system fatal." Example fix : Among 13 people, at least

• If-then → try contrapositive.
• “There exists” → construct an example.
• “For all” → choose an arbitrary element.

"Ms. Chen," Dr. Aris said softly. "Could you explain line 42?" He gestured to the crashed system on the screen
