First: linear operators don't have bases. Vector spaces (and subspaces) have bases. You'll note that the question does not ask for a basis for the linear operator, it asks for a basis of the range of τ τ, and for a basis of the nullspace of τ τ; and it so happens that both of those are vector spaces, so we can talk about bases for them.In today’s fast-paced digital world, time is of the essence. Whether you’re a student, professional, or simply someone who needs to crunch numbers on a daily basis, having a reliab...We should be checking that v1+v2 is in the nullspace. What it means to be in the nullspace is that A (v1+v2) should be the zero vector. But A (v1+v2)=Av1+Av2 (because matrix transformations are linear). Now if we assumed v1 and v2 are in the nullspace, we would have Av1=0 and Av2=0. So A (v1+v2)=Av1+Av2=0+0=0. A basis for the null space. In order to compute a basis for the null space of a matrix, one has to find the parametric vector form of the solutions of the homogeneous equation Ax = …This gives us: < →v, A→x > = 0. Which can be rewritten as: →vTA→x = 0 [→vT(A→x)]T = 0 since the LHS of the equation is just a 1x1 matrix. (A→x)T→v = 0 →xTAT→v = 0. Finally, we simplify to: < →x, AT→v > = 0 which doesn't seem to help.
