The zero vector 0 is in U 2. It may be obvious, but it is worth emphasizing that (in this course) we will consider spans of finite (and usually rather small) sets of vectors, but a span itself always contains infinitely many vectors (unless the set S consists of only the zero vector). The zero vector~0 is in S. 2. Calculate Pivots.
