Polar Line of a Point

Intersection of lines

Polar Point of a Line

On the left hand panel, again, we have the S shaped curve of adoption.

Points and lines

A point on the solution curve

What's the connection?

So this is what I want you to do, I want you to go through and start at Meryl Streep and move along the green lines here at the movies and each time you visit a movie, check it off as you go.

Inversion of Point, Line or Circle

Do you see?

The polar line of a point with respect to a conic.

Intersect with this line

The polar point of a line with respect to a conic.

So let's add a straight edge here, so this is to draw a line.

You can use the position parameter on the mesh class to re position the box, and in fact you'll need to do this for the exercise.

Let's call this line right over here line AB.

Select a point on the curve...

Hyperbola by Focuses Point

The midpoint of a segment or two other points

So that means that we're including the line.

And now we should be able to use this information to figure out the actual coordinates of the focus and the directrix of what I would call the classic parabola, y is equal to x squared.

Construct the polar line of this point

Check collinearity of this point

This is what it looks like.

Hyperbola by Asymptotes Point

Parabola by Directrix Focus

Check this box if you want URL links to be underlined.

So that's what this equation will look like.

Tangent at This Point

So all of these scores are made up of weather data.

So if this is 1, 2, 3, 1, 2.

Construct the midpoint of this segment

Start transport from this point of the line

Start transport from this point of the curve

Intersect with this conic

Intersect with this cubic

Construct the polar point of this line

Intersect with this cubic curve

It looks like a parabola.
