Hi,

how should i solve this?thanks

suppose A is a 3x5 matrix,and that Ax=b is a consistent system of equations for all b is an element of R^3.

Explain....what is the dimension of Col(A) and Null(A)?

You need the "dimension theorem" for Linear Algebra: If A is an n by n matrix, col(A)+ null(A)= n.

Now, what does "consistent system" mean when A if "3 X 5"? - Jun 14th 2013, 02:30 PMn22Re: coll and Null for examination
