OEIS Sequences

a(n) is the coefficient of xⁿ in the polynomial given by ∏_k>=1 (1 + prime(k)*x^k). A147655

Least k such that decimal representation of k·n contains only digits 0 and 2. A96681

Numbers k where |cos(k)| (or |cosec(k)| or |cot(k)|) decreases monotonically to 0; also numbers k where |tan(k)| (or |sec(k)|, or |sin(k)|) increases. A4112

Sin(n) decreases monotonically to -1. A46964

Expansion of ∏_k>=1 (1 + x^k²)^k². A291649
