Jan28 asked Geometric interpretation of a vector space and subspace? Jan28 accepted For which values is this a subspace? Jan28 comment For which values is this a subspace? A polynomial $P_a=a_0+a_1x+a_2x^2+...+a_nx^n$ s.t. $a_0,a_1,...,a_n=0$? Jan28 comment For which values is this a subspace? Unfortunately we haven't done linear maps yet, we can only solve this using the axioms. Jan28 comment For which values is this a subspace? But what exactly is the zero vector of $P^n$? Jan28 asked For which values is this a subspace? Jan26 accepted Prove this matrix is neither unipotent nor nilpotent. Jan26 asked Prove this matrix is neither unipotent nor nilpotent.
