Section 4.5 De nition 1. The dimension of a vector space V, denoted dim(V), is the number of vectors in a basis for V.We define the dimension of the vector space containing only the zero vector 0 to be 0. In a sense, the dimension of a vector space tells us how many vectors are needed to “build” the
