WebSo a basis for the null space of A is the vector (1/2, 1/2, 1). Since the nullity is the dimension of the null space, the nullity of A is 1. c) To find a basis for the range of A, we can find the pivot columns of the reduced row echelon form of A from part a). The pivot columns are the first and third columns of the matrix B. WebMar 5, 2024 · The rank of a linear transformation L is the dimension of its image, written rankL = dimL(V) = dimranL. The nullity of a linear transformation is the dimension of the kernel, written nulL = dimkerL. Theorem: Dimension formula Let L: V → W be a linear transformation, with V a finite-dimensional vector space. Then:
