WebThe result is essentially the rank-nullity theorem, which tells us that given a m by n matrix A, rank (A)+nullity (A)=n. Sal started off with a n by k matrix A but ended up with the equation rank (A transpose)+nullity (A transpose)=n. Notice that A transpose is a k by n matrix, so if we set A transpose equal to B where both matrices have the ... Web2. Solution: See Linear Algebra Done Right Solution Manual Chapter 3 Problem 25. 3. Solution: If there exists an invertible operator T ∈ L ( V) such that T u = S u for every u ∈ U, then S is injective since T is injective. If S is injective.

An arbitrary element of the vector space U + W is of the form x + y, where x ∈ U and y ∈ V. and hence x + y is in the span S := Span ( u 1, …, u n, v 1, …, v m). dim ( U + W) ≤ dim ( S) ≤ n + m = dim ( U) + dim ( V). This completes the proof.
