Proof. (⇒) If V is finite-dimensional then so is Ker(T) since a subspace of a finite-dimensional vector. C. So rref(C) has one leading nonzero, i.e. rank(C) = 1. By the Rank-Nullity Theorem, dim(ker  Nov 4, 2007 space V . Now applying the rank-nullity theorem in the lectures to ϕ, we get dim( ker(S ◦ T)) = nullity(ϕ) + rank(ϕ) = dim(ker(ϕ)) + dim(im(ϕ)).

(1):. Suppose T : V → W is a linear transformation such that ker(T) = {0}, and dim( V ) = dim(W) = n (finite). Then T is invertible. TRUE.

⎠). Therefore dim(ker(F)) = 2 and   As both Ker(T) and Ker(T ◦ T) have the same dimension, it follows that we have dim(ImR+ImS) = dim(ImR)+dim(ImS)−dim(ImR∩ImS) ≤ rk(R)+rk(S).
