That might simplify things.

And this should simplify things.

Just to simplify things a little bit.

And now we can simplify these things.

Now it looks like some things will simplify nicely.

So let's divide this numerator and this denominator by 3 to simplify things.

Then to simplify from this to that, he essentially canceled out both of these things.

Simplify

So to really simplify things for our head, you can kind of treat that like an atom.

When we set these variables to be these things, this whole thing would simplify to be 3.

Then simplify.

To simplify things, since we're actually dealing with a matrix, let's limit ourselves to the case of R2.

So actually, let me just kind of simplify things a little bit because we don't have to start here.

So the length of my vector y actually, let's do something even better. It'll simplify things a little bit.

Let's simplify this.

Now let's simplify.

Simplify the expression.

Simplify the expression.

let's simplify those.

We could simplify a little bit then rationalize, then simplify a little bit more, or we could just rationalize and simplify.

looks very complicated right now but now we just have to compute it, and dot products tend to simplify things a good bit so what is our matrix our product going to simplify to?

And now to find the perimeter is pretty straight forward, we just have to add these things up and simplify it

Now, to simplify things, let's multiply both this numerator and this denominator by 100, and that's so that 0.15 becomes 15.

Let me do that, and I'll do that in the next couple of videos because it'll simplify things, and I think make things a little bit easier to understand.

So we can simplify

So let's simplify this.

Now let's simplify this.

Let's just simplify this.

You could simplify it.

And let's simplify that.

We could simplify this.

Now simplify it more.

We could simplify that.

So let's simplify that.

I won't say simplify.

Then simplify the expression.

So let's simplify that.

Now, let's simplify this.

Now let's simplify it.

So let's simplify that.

So let's simplify this.

Then that will simplify matters.

Let's try to simplify this

I couldn't simplify this number.

We can't really simplify it.
