MATH 221: Subspaces, Basis, Dimension and Rank (4.1-4.3)
Examples of Subspaces (4.1)
If we start off with some vectors in a subspace S of Rn, then any linear combination of
those vectors must be in S too, since a subspace is closed under vector operations
because the -1 and T are exponents you can switch them so -1 and
-1 and next to each other and the T and T are next to each other
A(I-X) = BX for X what do u have to assume is invertible ?
always think of it like regular algebra but follow the rules of ma
