Something really weird is going on here.

We know that the baseline is 0.2 mm, and the object is 50 meters away.

Or they can be, I don't want to say always.

And this is f2.

And it's for focus.

Check one.

So let's call that a directrix.

That's our directrix and it has the equation y is equal to k.

We have focused on the worst case scenario.

And what we want to do is, we want to find out the coordinates of the focal points.

Ellipse by Focuses Point

Requires great focus.

Focal length of the lens

Well, we just used the distance formula.

Just focus.

Bifocals.

Your focus,

Hyperbola by Focuses Point

So let's solve for the focal length.

And hard to keep focus.

Focal Length

Telescope focal length

Eyepiece focal length

I'll call that well, we'll call that a focus because it will be a focus.

But where's the focus point?

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.

The scaling factor was 1.

I'll do it on this right one here.

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

35mm equivalent focal length

That's this distance right there.

And that's what we set out to figure out in the beginning.

And you enter that space, and you feel like, Wow!

We focus on Parker. And move it.

Or b which is, remember, what was b?

Just remember, you're going 1 over 4A below the vertex.
