14 Properties of Vector Spaces :

15 Subspaces of Vector Spaces:
Check to see if there are any properties inherited from V:

16 Subspace Criterion in two forms:

17 More Examples: The set of all symmetric matrices. The set of all lower triangular matrices. The set of all upper triangular matrices. The set of all diagonal matrices.

18 Example: Subset of the Vector Space That is Not a Subspace

19 Example: Lines and Planes Through the Origin as Subspaces of R2 and R3

20

21 The Intersection of Subspaces

22 The Span of the Set of Vectors

23 Example: Spaces Spanned by One or Two Vectors in 3-space
Span of a subset in V is a subspace of V:

24 Exercises: Determine if the following are subspaces of Mnxn.
