Hello everyone! Can anyone help me here in this theorems (prove)?(adsbygoogle = window.adsbygoogle || []).push({});

(Or solve)

1. Suppose that A and B are square matrices and AB = 0. (as in zero matrix) If B is nonsingular, find A.

2. Show that if A is nonsingular symmetric matrix, then A^-1

is symmetric.

I hope these won't bother...
