- List a set of three vectors in R2 that spans R2 from which you can any remove any two of the vectors and still span R² with the remaining one vector. List a set of three vectors in R2 that spans R2 from which you can remove either of two particular vectors and still span R² with the remaining two vectors. However, if you remove the third vector, the remaining two vectors will not span R². State which vectors can and can't be removed.
