A Matrix is singular (not invertible) if and only if its determinant is null. By the properties of the determinant: det ( A) = det ( A T) And by Binet's theorem: det ( A ⋅ B) = det ( A) det ( B) Then, you're requesting that: det ( X T X) = 0. det ( X T) det ( X) = det ( X) 2 = 0. Webgeometric intuition of what these tools represent. Linear systems offer a powerful application of the ideas seen so far, and lead onto the introduction of subspaces, linear independence, bases, and rank. Investigation then focuses on the algebraic properties of matrices that illuminate the geometry of the linear transformations that they represent. immigration think tanks
