It s reverse racism against whites.

It's just the inverse operation.

This statement doesn't let us go the other way.

So an identity matrix is a matrix.

Let's just do some matrix matrix products.

A 2 by 3 matrix, a 2 by 3 times 3 by 2 matrix, I got a 2 by 2 matrix.

The identity matrix times any other matrix is just that matrix.

So in general, the nullity of any matrix of any matrix

So it's a 2 by 3 matrix.

Anything times that identity matrix is going to be equal to itself.

This is counterproductive.

It's actually going to be a 3 by 3 matrix, a much bigger matrix.

Depending on the permitted criteria for the award of a contract procured through ERAs, two systems are found those based on the lowest price alone and those that permit additional criteria.

This time, however, the plan backfired.

That position is flawed and counterproductive.

It's not like they're gonna end on an upward panning shot...

In mathematics, an integer matrix is a matrix whose entries are all integers.

This is equal to some new matrix I'll make it pretty big right here times our vector x .

Or, we would call this matrix, just by convention, you would call this a two by three matrix.

We have a 3 by 2, times a 2 by 3 matrix, so it's going to result in a 3 by 3 matrix.

I get the k by k identity matrix. I get the identity matrix of k, because it's going to be k by n, times n by k.

So that's my original A right there.

OK, so the matrix of cofactors is essentially applying this pattern to the matrix of minors.

Array of tools

I will create an augmented matrix.

It's a diagonal matrix.

Matrix of minors.

To figure out its transformation matrix, so if we say that T of x is equal to, I don't know, let's call it some matrix S times x.

On the contrary, they can have opposite effects.

This is a reverse view of things from the kind of traditional Romantic view.

You will have seen something like this this is the reverse effect.

If we have a 2x2 matrix, the identity matrix is 1, 0, 0, 1.

The transformation matrix with respect to that eigenbasis, it becomes a very, very nice matrix.

We multiplied the 3 by 2 matrix times a 2 by 3 matrix, and we got a 3 by 3 matrix.

I could just create a coefficient matrix, where the coefficient matrix would just be, let me write it neatly, the coefficient matrix would just be the coefficients on the left hand side of these linear equations.

Well our change of basis matrix is just the matrix with these guys as the columns.

We have a 3 by 4 this right here is a 3 by 4 matrix, and this guy right here is a member of R2.

So the reason why I'm going all this is because we just did a matrix matrix product up here.

This times this will equal the identity matrix.

And it turns out there is such a matrix.

So it's an m by n matrix.

So, let me draw a matrix for you.

That is a five by two matrix.
