The color for the angular distance measurement ruler.

We're not measuring how much area we're taking up.

So you add 8 to itself 4 times, that's the same thing as 8 times 4, you get 36 meters.

Measure the distance between two points

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

We use a lot of laser range finders.

Given the following set of 10 range measurements, what is the 95 confidence interval for the actual distance?

We're here, and the other point is up here.

And when he pulled the trigger, they'll run for the projectile.

Readouts are as follows

Oh man, I have a shaky hand.

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

Using this pointer, made out of reflective markers,

Misjudged the distance.

Readouts are as follows...

So it would be the distance around.

The length of the arrow is the absolute value of this.

So this is really the key step. It is finding the distance of the shortest path.

So the absolute value of 3 minus 4i is going to be the distance between 0, between the origin on the complex plane, and that point, and the point 3 minus 4i.

I'm going to measure it's distance to each of my cluster centroids, this is mu and then

Use my results as a baseline.

Let me make the point, again here's our 4 landmarks, and we measure the distances to those.

And we learned that the focus, the focal distance or the distance from the central of the ellipse, which is this distance right here that focal distance is just the square root of the difference of these two numbers.

Let's now go to a difficult challenging case where I'd like to recover the focal length f from measurements of the type z, delta x, and B.

These two focal lengths are symmetric.

Isolate discontinuities and recalibrate.

You don't really have to consider them.

Which require callibration from somewhere else.

light blue distance?

Our Google self driving car uses radar on the front bumper that measures the distance to vehicles and also gives a noisy estimate of the velocity.

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.

Proper motions of stars, can also be used. Looking at statistical sense.

So let's just put zero right over here, since we are taking the distance from 0.

And then I have this distance over here, so I'm taking any point on that ellipse, or this particular point, and I'm measuring the distance to each of these two foci.

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

In practice, what we tend to do is we go more like this.

At a distance of

Distance

For the sake of this question, we're going to just consider delta x, which is x2 minus x1 the displacement in the corresponding images.

That's just this distance right here.

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