• Day algorithm [more] • The fifth twelve literacy: What is to reconcile the number?

Preface ▎

　　Xiao Bian already heard this thing, but I do not know what to reconcile the number of yes.

　　In fact, Xiao Bian heard more harmonic series, and then reconcile the number of the harmonic series are to talk about it.

▎ defined

　　Reconcile this kind of number is long:

　　

　　Is 1/1 + 1/2 + 1/3 + 1/4 + ...... + 1 values ​​/ k a.

▎ harmonic progression

　　To reconcile the number of visible very simple.

　　Harmonic progression is to define the infinite.

　　Harmonic Series is value.

▎ divergent harmonic series

　　This is very simple, as long as know the law on it.

　　

　　So the final value is:

　　

　　So the result is infinite, we call diverge.
