it is supposed to be
0, 1
1, 0

Let B=
0 1
1 0
Find B if it is to the negative one power. (Its supposed to be a matrix, but I don't know how to write the brackets on the computer)

In other words find the inverse matrix?
0,1
1,0
times
a,b
c,d
equals identity matrix
1,0
0,1
then
c = 1
d = 0
a = 0
b = 1
so
0,1
1,0
In other words, it is its own inverse
