Question
It can be shown that A and B are elements of the group of 2 x 2 invertible matrices with real entries under the binary operation of matrix multiplication. Show 3. Let A = and B = that A and B have finite orders but AB does not. Recall that the order of an element in a group is the number of times that it must be combined with itself in order to produce the identity element.
