This focal length is f.

Show camera aperture and focal length

Print camera aperture and focal length

What does that focal length do?

That distance is the focal length.

So we have the focal length.

So let's solve for the focal length.

And then he said, This is the focal length.

And the focal length this a squared plus b square.

So the focal length is equal to the square root of 5.

Show the camera aperture and focal length at the bottom of the screen.

Or the focal length squared minus a squared is equal to b squared.

The focal length, f squared, is equal to a squared minus b squared.

And all I did is, I took the focal length and I subtracted

But this is a five meter telescope has about a quarter mile focal length.

And this of course is the focal length that we're trying to figure out.

Which tells us that the focal length is equal to the square root of this.

The focal length is equal to the square root of a squared plus b squared.

What we just showed you, or hopefully I showed you, that the the focal length or this distance, f, the focal length is just equal to the square root of the difference between these two numbers, right?

We learned that the focal length is equal to the square root of a squared minus b squared.

The concept of differentiating and categorizing the focal points according to developed and developing countries was debated at length.

So hopefully you're now satisfied that the focal length of a hyperbola is the sum of these two denominators.

So, f, the focal length, is going to be equal to the square root of a squared minus d squared.

I just factor out the x squared there, minus y squared is equal to f squared, the focal length squared, minus a squared.

One day he took us out into the sun and tried to show us how to find the focal length of a convex lens.

So this work is nothing but like because of the focal length of the lens, it just shows what is on the other side.

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.

So I just put the paper on the focal length, which was an etching print, then I got the portrait of the sun from sunlight.

Now, let's see if we can use that to apply it to some some real problems where they might ask you, hey, find the focal length.

That length minus that length over there

This length is equal to this length.

That side length is equal to that side length, is equal to that side length, is equal to that side length
