WebbThis first part of the fundamental theorem of linear algebra is sometimes referred to by name as the rank-nullity theorem. Part 2: The second part of the fundamental theorem of linear algebra relates the fundamental subspaces more directly: The nullspace and row space are orthogonal. The left nullspace and the column space are also orthogonal. WebbThe goal of this exercise is to give an alternate proof of the Rank-Nullity Theorem without using row reduction. For this exercise, let V and W be subspaces of Rn and Rm respectively and let T:V→W be a linear transformation. The equality we would like to prove is dim (kernel (T))+dim (range (T))=dim (V) Let {z1,…,zk} be a basis of ker (T ...

WebbRank-nullity Intuitively, the kernel measures how much the linear transformation T T collapses the domain {\mathbb R}^n. Rn. If the kernel is trivial, so that T T does not collapse the domain, then T T is injective (as shown in the previous section); so T T embeds {\mathbb R}^n Rn into {\mathbb R}^m.
