WebApr 19, 2024 · Have to show these are linearly independent, without any row-echelon matrix. I know that the rows are dependent if [MATH]detA = 0 [/MATH], so I've gotta prove the opposite. I see only 2 ways of finding the determinant -- out of the ones we've covered so far: 1) I'm hesitating to use the Triangle method, since we have unknowns. WebTo express a plane, you would use a basis (minimum number of vectors in a set required to fill the subspace) of two vectors. The two vectors would be linearly independent. So the span of the plane would be span (V1,V2). To express where it is in 3 dimensions, you would need a minimum, basis, of 3 independently linear vectors, span (V1,V2,V3).
