Hi!
My name is Jose and even though I'm not smart enough to be an engineer, but I've always enjoyed the design aspect of it (probably that's why I became a graphic designer). I also like to invent stuff in general. I am joining PF because it seemed like an honest and down-to-earth forum...
Hi guys!

I made some tweaks to the diagram you may have seen me post in threads about delayed erasure.
Let me know what you think, what's confusing, etc.
Here's the updated version:
And the old version:
y = a x² + b x + c is a parabola. But, a parabola is just a kind of conic.
All conics are given by a x² + b x y + c y² + d x + e y + f = 0
The same way, the graphic y = f(x), with f(x) satisfying a d²f/dx² + b df/dx + c f = 0, is just a particular graphic of F(x,y) = 0 with F(x,y) satisfying...
