- Let (xn) be a
bounded sequence ((xn) is not necessarily convergent), and assume
that yn → 0. Show that lim n→∞ (xnyn) = 0.
Question1.
All the
solution state that there exists M >0 and xn<=M . My question
is that why M always be bigger than 0 and Why it is bounded above ?
why it is not m<=xn bounded below????

Oh, and I would appreciate it if you could tell the answer using
computer typing instead of handwriting.
Because I don't know the cursive
If it is difficult, I would appreciate it if you could respond
in a convenient way.
