Let W be the set of all (X1, X2, X3, X4, X5) in R5 which satisfy
Find a finite set of vectors which spans W
Does this mean I have to find the vectors such that
c1V1+c2V2+c3V3+c4V4+c5V5=(X1, X2, X3, X4, X5) for some uknown V? And if so, what's the best way to go about it, by row-reducing the matrix above?
