WebbA sequence ( a n) diverges if for any x ∈ R there is a neighbourhood V ( or ϵ > 0) such that given any n ∈ N there is a corresponding natural number m n ≥ n such that a m n ∉ V (or … WebbVi skulle vilja visa dig en beskrivning här men webbplatsen du tittar på tillåter inte detta.
WebbThe divergence test is a conditional if-then statement. If the antecedent of the divergence test fails (i.e. the sequence does converge to zero) then the series may or may not … WebbSimilarly, it turns out that the sequence of partial sums of 1/n increases to positive infinity. Given any number, if you add up enough terms, you will eventually get larger than that …
