Lecture 8 - HMC Math
... Since A~x = ~0 has only the trivial solution ~x = ~0, by the Fundamental Thm of Inverses, we have that A is invertible, i.e., A−1 exists. Thus, (BA)A−1 = IA−1 =⇒ B (AA−1) = A−1 =⇒ B = A−1. | {z } I ...

... This second result confirms the case when x is a scalar and x ! 0 , then x n does not converge. Again, we see some relationship between a determinant of a matrix and the absolute value of a scalar. The last thing on the agenda for this lecture is to do a problem working with matrices. You will have ...

... A.3. Rank Definition. The rank of a matrix is the number of pivots in its reduced row-echelon form. Note that the rank of an m × n matrix cannot be bigger than m, since you can’t have more than one pivot per row. It also can’t be bigger than n, since you can’t have more than one pivot per column. If ...
