Circular Selection

So let's call that point right over there and let's call that D. And let's say you have a line and the only point on the circle that the only point in the set of all the points that are equal distance from A, the only point on that circle that is also on that line is point D. And we could call that line, line L. So sometimes you will see lines specified by some of the points on them.

So this circle with a dot in the middle tells we're talking about circle, and this is a circle centered at point A. I want to be very clear.

Geometric Maltese Cross

Geometric Curved Four Point Star

Geometric Quarter Circle

Geometric Perfect Circle

Of course not.

It's the sand of the Colosseum.

About a billion miles away, here's what happens to Earth's orbit it becomes elliptical instead of circular.

Tom has a bald spot.

Why on earth are they called conic sections?

Next, this direction doesn't really matter.

I have a round bald spot on my head.

So this is still elliptical shapes.

So here's an example of a contour figure, shown on the right, where the axis are theta zero and theta one.

Let's say this is the center of the object path, the center of the circle

It's not a line.

The points on the circle are the points equal distant from point A. Now, L is tangent because it only intersects the circle in one point.

It's the, uh, boxylooking thing with the, um, circular doorlike thing on the front.

You have to have points B and C before you can draw those equal arcs.

Conical

And the question is, is sigma circular, which would be like this, or elongated, which would be like this or like this?

Yeah, that's what we said. That was the first step.

The orbit around Sirius is elliptical.

So Earth's orbit maybe looks something like that.

Can you give me the definition of a cone?

Point to Point

Mr. Marvel, released, suddenly dropped to the ground and made an attempt to crawl behind the legs of the fighting men.

Scott Stoddard has 27 points in the championship exactly the same as JeanPierre Sarti.

Are there any other rays of light that could make it into the eye?

Power of shape here's a whale. We've seen that the fins of this whale have tubercles on them.

And what we see is a line of stars.

F to H through A. (That's about as straight as I could draw it.) So if you have a chord like that, that contains actual center of the circle, of course it goes from one point to another point of the circle, and it goes through the center of the circle, we call that a diameter of a circle.

So there's a whole ray of light rays of light on a cone that will all be bent by that cluster and make it into the observer's eye.

There was a sound of many footsteps, and

The Japanese pride themselves on Mt. Fuji, a cone shaped mountain.
