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
