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). Web5. The General Solution of the Homogeneous Linear Differential Equation of Order n We have hinted that the general solution of (1) is a linear combination of linearly in-dependent solutions of (1).
