Same thing, that's this line.

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.

And the circle is really just a special case of an ellipse.

By definition, a circle is all of the points that are equal distant from the center point.

Remember, the circle itself is all the points that are equal distance from the center.

So this so far, all we've shown to you is if we do take the

The two distances are the same.

So this distance up here is 45vb.

So another way of saying it, this thing right over here is going to be equal to 5.

And it also gels with what we know.

Check if this point has the same distance

Now let's see what other points.

This point and the regression line, that's the prediction error or residual for that individual.

Point blank range.

And the actually equation, we actually just took an arbitrary xy in the coordinate plane, and we said that xy has to satisfy the condition that its distance to this focus is equal to that this distance right here is equal to this distance here.

I mean, by definition, work is equal to this force times this distance that I'm applying the block that

So it would be the distance around.

For all of the points in the xy plane that satisfy the conditions that its distance to the focus is equal to the distance to this line.

So how do we figure that out? Well if we say Beth's distance, let's use the letter B for shorthand.

Select the point which might have the same distance from two other points...

The two distances are not the same.

That's this distance right there.

Probably the distance.

Shots at close range.

And once again, just as review, a circle, all of the points on the circle are equidistant from the center.

It's just the square root of 9 minus 4.

So a circle is a special case of this, because in a circle's case, the furthest we get from the origin is the same distance as the closest we get, or, in other words, we are always the exact same distance away from the origin.

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

Using this pointer, made out of reflective markers,

So how many meters?

What is the distance?

They still have to climb down to the middle terrace.

Or in this case, you can kind of say that the major axis and the minor axis are the same distance, that there isn't any distinction between the two.

At a distance of

Distance

We use a lot of laser range finders.

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

So one of the first things someone might want to ask is what is that distance, that equal distance that everything is from the center?

These two focal lengths are symmetric.

Now let's go the other way around,

Test whether a given point have the same distance from a given point and from another given point

Long distance?
