WebSo we don't know, necessarily, whether it's invertible and all of that. But maybe we can construct an invertible matrix with it. So, let's study a transpose times a. a transpose times a. A is an n by k matrix. A transpose will be a k by n matrix. So, A transpose a is going to be a k by k matrix. WebCorrect option is D) If A is a square matrix, then and if A represents its transpose, then. A+A is symmetric and A−A is skew symmetric. Hence matrix A can be written as. A=( 2A+A)+( 2A−A) Therefore of all the above matrix, A−A is not symmetric. Solve any question of Matrices with:-. Patterns of problems.
