And this is f2.

And it's for focus.

It's equidistant from a focus and a directrix, where this is the focus.

It looks something like that.

So there's one point that just by looking at it we could say is going to be in our locus.

Though graphics hardware can definitely accelerate image processing operations. We'll mostly be focused on 3d rendering in this course.

So let's call that a directrix.

Let's take it right there.

So, if this point right here is the point, and we already showed that, this is the point the center of the ellipse is the point 1, minus 2.

We also know that the projection of the building on the internal chip is 4mm in size.

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

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

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

This doesn't cause any damage.

And let's say I have some other point.

So what's the reality?

Let's focus on the conversations between our friends and our family and our coworkers and our loved ones.

And it's a center, a focal point for economic and social development.

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

But where's the focus point?

I'll do it on this right one here.

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

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 directrix is going to be there, the focal point is there.

And hard to keep focus.

So 1 over 4 times 2 is equal to 1 8.

We have focused on the worst case scenario.

And you essentially divide 1 by 4 times this value.

So there is a big issue with cooperation and mutual care, inside the home as well.

Or b which is, remember, what was b?

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

This is f1, this is f2.
