How statement and proof provenance work
The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.
- Literature-sourced: the exact statement appears in a cited source; only wording and notation differ.
- AI-adapted: a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
- AI-generated: a genuinely novel statement formulated by AI, with no source for the claim itself.
These labels describe origin, not correctness: citations and verification chips remain separate evidence.
False: any positive zero of sine characterizes pi
Statement
If and , then .
Facts & Assumptions
Given: The proposed implication for positive sine zeros.
The number is positive (Pi as twice the smallest positive zero of cosine).
The least positive zero of sine is (Pi is equivalently the first sine zero, twice the first cosine zero, and half the least common period).
For every real , if and only if for some integer (The zero sets of sine and cosine and the least positive common period 2 pi).
Refutation
Put . By [L1], , and by [L3], .
Yet because .
Thus a positive zero need not equal . The correct characterization in [L2] requires the least positive zero.
