MA351 MA 351 Homework 8

(Copied from User_talk:wang403.)

3.2 #24

When a vector [V] is in the span of Ker(A), it means that the linear transformation of [V]([A])=the zero vector.

So... The vector that makes the vector A zero is in the span of Ker(A)

3.2 #28

Use theorem 3.2.4.

But first determine whether each column is linearly independent.

3.2 #45

Use summary 3.1.8 on Pg. 109

Note that ker(A)=zero vector, that means all columns in A are linearly independent.

3.3 #28

to form a basis of R4, the RREF of A must be I4.
