Which is what?

I will compute what's called the expected or average number of friends.

If b was greater, it would be the major radius.

Middle of week

Midtwenties.

last video to say oh, the sum of the distance between this and this, that sum, is going to be equal to, we saw, is going to be equal to 2a, or the distance of the semi major axis.

This is true because we're just checking equality.

So, we're not referring to anything in the real world.

And then of course, I blame the Soviet Union.

I was really seeking action without feeling.

We're only halfway there.

Well begun is half done.

And of course this point right here this will be a, so this would be the point minus a comma 0.

I was going to miss my game shows.

We ended up even with frost deep into Mexico.

How to know?

And I say, Nope. I have proof.

It's the middle of the afternoon.

Let's call our function gcd. It takes 2 inputst that are integers a and b.

And then this is the height, this is the height, right over here.

I have to add b minus a.

Well begun is half done.

We know that a radius connects a point to the center, so you have one radius right over here that connects F and A that's one radius and you have another radius connecting A and H, a point connecting to the center of the circle.

We're actually adding a's and b's together, but a is odd, so let's pull one of the b's out and add to that, well what's left there is a minus 1, repetitions of b that we're adding together, but a minus 1 is now even, so we can have that compute what a minus 1 over 2 times b is recursively.

It's just the distance from the center out to the edge.

Let me give you an example.

And, you know, it happens for several reasons.

White male, mid thirties. Is considered highly dangerous.

What you do is you say well this b a, this corresponds to the 2a term, so a is going to be half of this, is going to be half of this coefficient.

Literature flourishes best when it is half a trade and half an art.

We know in regular mathematics, if I have 1 times a, I get a.

We're going to reserve a proof for it for an algebra class that you might take in college or in high school.

I should've worn a short sleeved shirt.

I should've worn a short sleeve shirt.

I should've worn short sleeves.

I wish I'd worn short sleeves.

And we actually did that and it gave us a competitive advantage for a while.

We can imagine framing this as some hypothetical procedure optimization okay.

And this would be true wherever you go along the whole ellipse, and we learned in the last video that this quantity is actually going to be equal to 2a, where a is the distance of the semi major radius.

Because b is smaller than a.

I had to get myself three injections a week for a year and a half.

Yeah, I lived there till I was in my mid20s.

He's semiretired.

Is there some a and b where a plus b is equal to 10?

And if that doesn't make sense to you, watch the Khan Academy video on completing the square.
