Thread starter M55ikael Start date Dec 1, Homework Statement I can't for the life of me figure out how to do this.

The attempt at a solution I've figured out that the determinant is zero, so in its current form it's definitely not a basis. At least one of the vectors are obsolete, and they don't span R4. I was going to take away a vector at random and see if the remaining vectors were linearly dependant or not, but I'm not sure how to prove that a non square matrix is linearly independent.

Example: Say I take away one vector and use gauss-jordan elimination on the matrix comprised of the remaining vectors. I would eventually end up with all the constants equal to zero, or one or more rows of zeros. But if I ended up with an identity matrix, it wouldn't actually prove that the ONLY solution was that alle the constants are zero, would it?

This is my first postso please be kind ;- Thanks for helping me out! EDIT: Sorry, this might have been better suited for the physics sub-forum.

Rsu grant strike priceI am just stuck and have no clue as to what I am looking for. Our text is custum and does not have an example of this but it does have examples of finding the basis of row space, column space, and null cpace of a matrix. Is this the same thing? Please Help! Thank you in advance!!! Remember to find a basis, we need to find which vectors are linear independent. So take the set and form the matrix Now use Gaussian Elimination to row reduce the matrix Swap rows 2 and 3 Replace row 3 with the sum of rows 1 and 3 ie add rows 1 and 3 Replace row 3 with the sum of rows 2 and 3 ie add rows 2 and 3 Replace row 1 with the sum of rows 1 and 2 ie add rows 1 and 2 Now the matrix in reduced row echelon form.

Notice the matrix only has 2 pivot columns which are the first two columns. This means the first two columns of the original matrix are linearly independent. Since the third column does not have a pivot, it is dependent on the first two columns So to form a basis, simply pull out the linearly independent columns of the original set of vectors to get the set this set will span the original set since taking out a dependent vector does not change the span.

Also since the set is linearly independent, this set forms a basis since both properties are satisfied So the basis is: If this isn't what you're looking for, just let me know.Add to solve later Sponsored Links. We apply the leading 1 method.
