Then if I take the composition of h with f, I have to get the identity matrix on the set X.
I'm essentially multiplying-- when you combine all of these-- a inverse times the identity matrix.
So any inverse, so we're saying that g is a situation that if you take the composition of g with f, you get the identity matrix.
We start with the identity matrix, and we apply the transformation to every column of the identity matrix.
So before we introduce that, I'm going to introduce you to the concept of an identity matrix.
So all we do to figure out C is we start off with the identity matrix.
So let's confirm that that times this, or this times that, is really equal to the identity matrix.
Our second column of C is going to be B times A times the second column of our identity matrix.
And you could try it the other way around to confirm that if you multiply it the other way, you would also get the identity matrix.
And if you get a row of 0's, you're never going to be able get the identity matrix.
So the identity matrix-- I will draw it really small like this-- the identity matrix looks like this, 1, 0, 0, 0, 1, 0, 0, 0, 1.
So what we're going to do is we're going to start with the identity matrix, identity 2 because that's my domain and it just looks like this.
We got the identity matrix.
Well that's just the identity matrix.
And that's the identity matrix.
The identity matrix looks like this.
Where I'm left with the identity matrix?
You're going to get the identity matrix.
And what's the transpose of the identity matrix?
A-inverse times A has to be equal to the identity matrix.
