Hello everyone, its me.(adsbygoogle = window.adsbygoogle || []).push({});

I had a question again:

I was suppose to determine if these vectors, A, B, and C, and D Linear Independant, Well A, B, C are linear independant, but D is not, I got

D =

3/5

-4/5

-1/5

0

A =

1

0

0

0

B =

0

1

0

0

C =

0

0

1

0

I row reduced and got:

1 0 0

0 1 0

0 0 1

If they are linearly dependent, determine a non-trivial linear relation - (a non-trivial relation is three numbers which are not all three zero.) Otherwise, if the vectors are linearly independent, enter 0's for the coefficients, since that relationship always holds.

A + B + C + D = 0.

So they want me to find Coefficents that make A + B +C +D= 0, and i'm confused on how i'm suppose to do that! Thanks!
