- Suppose that S1 and S2 are subspaces of a vector space (V, F). Show that their intersection S1 ∩ S2 is also a subspace of (V, F). Is their union S1 ∪ S2 always a subspace?arrow_forward10.Suppose that each of the vectors x(1), …, x(m) has n components, where n < m. Show that x(1), …, x(m) are linearly dependent. In each of Problems 11 and 12, determine whether the members of the given set of vectors are linearly independent for −∞ < t < ∞ . If they are linearly dependent, find the linear relation among them.arrow_forwardDo questions 53 and 54 Show if it is a subspace using these 3 steps: 1. has to be equal to the 0 vector 2. has to be closed under addition 3. has to be closed under mulitplicationarrow_forward

Find and interpret T ' ( n ) .arrow_forward
- For Problem #12, how do I prove that the set is a basis for V? I think that infinity is the basis, but I'm not sure. This is a Linear Algebra type of question. Here is a picture.arrow_forwardIf A is m by n, how many separate multiplications are involved when(a) A multiplies a vector x with n components?(b) A multiplies an n by p matrix B?( c) A multiplies itself to produce A2 ?
