WebTwo vectors that are linearly independent by definition will always span R2. The claim that "we can take almost any two vectors... they will span R2.." is incorrect. We can take any two vectors that are LINEARLY INDEPENDENT and they will span R2. Two zero vectors are not linearly independent. WebThis illustration is just two vectors in R2 and the span of those two vectors is all of R2. That is, I can define any point on the plane here or here, or here. I can define any one of those points as being some linear combination of this vector v1 and this vector v2. Simply, the plane R2 is spanned by the vectors 1, 0 and 0, 1. Easy.
