In love, we want to have, we want to know the beloved.

This is what we need to know.

So it would be that distance plus that distance plus that distance plus that distance.

These two focal lengths are symmetric.

We use a lot of laser range finders.

So instead of that, we multiply that with speed of light, converting it into a distance.

So if you multiply 30 times here and times thirty, this is the distance.

So it would be the distance around.

If it's in meters per minute, then this is the distance in meters.

So if this distance is the same as this distance, then the magenta distance minus this blue distance is going to be equal to this green distance.

light blue distance?

So 1 2 times 3 times 4.

It's a square.

That's just this distance right here.

So this distance up here is 45vb.

And obviously these guys are even further.

Set here equivalent focal length assuming a 35mm film camera, in mm. A value of 0 means the focal length is unknown.

So if we use a camera, I use a different model than if we use a range finder.

Now, the next most interesting thing that you might be wondering about a circle is how far is it around the circle?

I have a triangle like this.

Well, the first thing you do is though I've never well, we could just figure out the focal length just by plugging into the formula.

So that's 15 fewer km.. And so the number of km that Beth ran would be this distance right over here.

Let's call this distance d1.

If he's on one of these roads... he's in for a short trip.

We're already making the claim that the distance from here to here, let me draw that in another color.

So let's just leave that unlabeled right now.

What's this distance right here? d sub 1.

The distance of this point to the image plane up uppercase Z.

Now on this next day, she's 50 minutes late.

As we get really far away, the stars are predicted to move slowly again.

This is what delta x is right now.

But I have a strong feeling he'll be there. ( ominous theme playing ) How far is it?

2200 feet.

How much further?

How far?
