The sequence b(n)= npicos(npi) coverges or diverges? if it converges what is the limit?(adsbygoogle = window.adsbygoogle || []).push({});

My Work

When n is even cosnpi= o and b(n)=o (therefore when n is oven it converges)

but

when n is odd cosnpi=-1 and b(n)= - infinity( thereofre when n is even it diverges)

is this correct?
