1.4. SUBSPACES OF A VECTOR SPACE 11 the corresponding vector is a = (a11, α, α, a22) and we have the unique representation a = a11e·1 + αe∗ + a22e·4. Because the basis for this vector space has three elements, the dimension of the space is three. Thus, these special ...
Which of the following are vector subspaces of R3? Let P_2 denote the vector space of all polynomials with degree less than or equal to 2. A) Show that B = (1 + x + x^2 , 1 + 2x - x^2 , 1 - 2x - x^2) is a basis for P2. B) Find the coordinate vec ...
Determining if specific instances of these sets are vector spaces leads to other linear algebra topics, such as subspaces, linear independence or dependence of vectors, basis, rank, and dimension. A technology section on applying a theorem about matrix rank to determine consistency of systems of ...
Subspaces allow a layering of sets of increasingly regular vectors while preserving the linear structure of the space. For example, the set C1[a,b] of all real-valued functions on [a,b] which also have a continuous derivative is a subspace of C[a,b], while C20[a,b], the space of ...
