Thank you David!

If 10ft away from the beamer the image occupies 10ft x 10ft, 15ft away the image is 15ft x 15ft big.

Glad that observation was of help.
Your result follows from similar triangles, but refocussing alters
the angles of the triangle (slightly)

Well Retina amazing isn't it ? That one numerical example I gave the forum is enough. And that's without a comp, just my scientific calculator

But thats merely the tip of the iceberg, pal! It is only an offshoot of my Beth Theorem. With it I can give an infinite number of examples. You have the integers and I have the equations.

There is a saying among mathematicians that one can only reach his peak in the twenties. After that one starts going down hill. You can now add that there are exceptions to this rule.

Well it is said "genius is 1 % inspiration, 99 % persperation" True! very true!

It all depends what you do with the 1% inspiration !

Its all a matter of attitude.

Here is a saying I couldn't find on the Net.

Two men looked out of prison bars,
One saw the earth below,
The other the stars.

BTW: My inspiration is from the Holy Spirit of God.

P.S. I have just come across Xyzzy's post in "A simple question' (?)

I think thats the best answer to you

I somehow recall other examples of ambiguity in the presentation of
this poser's problems.
The ambiguity is often the only source of interest in the problem.

PS I note I referred to him as "poser". Most appropriate methinks

It won't be a picture, cause it is out of focus. Now if you wanted to know the size of the blur....
