WebIf the Kernel of a Matrix A is Trivial, then ATA is Invertible Let A be an m × n real matrix. Then the kernel of A is defined as ker(A) = {x ∈ Rn ∣ Ax = 0}. The kernel is also called the null space of A. Suppose that A is an m × n real matrix such that ker(A) = 0. Prove that ATA is […] Is an Eigenvector of a Matrix an Eigenvector of its Inverse? WebFeb 3, 2015 · Now a reasonable step would be to divide the last row by ( k − 1). But this is only possible if k − 1 ≠ 0. So you can: Solve the case k = 1 separately. For k ≠ 1 divide the last row by ( k − 1) which leads you to a simpler matrix - you should try whether you are able to continue from there.
