turingtest · Answer

put them in a matrix and row-reduce
each row after elimination is a basis vector

turingtest · Answer

at least one row should eliminate completely to the zero vector

anonymous · Answer

i got one row that is completely eliminated to the zero vector

anonymous · Answer

now  what do i do?

turingtest · Answer

what about the other remaining vectors?
what do you get when they are completely reduced?

anonymous · Answer

1 0 -6 3
0 1 3 0
0 0 5 -13
0 0 0 0

i don' know if this is right.
