Gold Parabola calculator (win)

a web reference for this please.

(it is in the rules)

 

Yes you’re right,, but unfortunately there is nowhere on web anymore..

 

The "focus point" has nothing to do with photography. That's the parabola focus point, that's mathematics man, beautiful but totally unrelated with photography

 

OK. then you might state that in your post. and if it is unrelated to photography, perhaps post in Other forum

 

"Ikngood, I'm not the original poster, I'm just remarking how inappropriate is the post by making clear that focus point is a mathematical term

 

Hey guys,, of course it’s relayed to photography (too)
-meaning the focus point of a parabolic light shaping tool - the point that rays of light travels parallel, and of course it’s mathematics

 

Understood, but honestly it sounded misleading, and the lack of a reference link didn't help either
