Limit of two convergent sequences Let xn, yn be two convergent sequences. Show that limn-->∞xnyn exists. Since the sequences converge, they have (finite) limits. Let $\displaystyle \lim_{n \to \infty} x_n = x$ and $\displaystyle \lim_{n \to \infty} y_n = y$ We will not only show that the limit of the product exists, b...
