The '''Bolzano-Weierstrass theorem''' is an extremely important theorem of [[real analysis]] in [[mathematics]]. It states that any infinite, bounded set of [[real numbers]] has an [[accumulation point]]. Equivalently, it states that any bounded infinite sequence of real numbers has a subsequence that converges. | The '''Bolzano-Weierstrass theorem''' is an extremely important theorem of [[real analysis]] in [[mathematics]].
