Hi,
Your typical funciton looks something like this in math books:
f(x) = A*x + x^2 //just an example
Where f(x) is essentially 'y'. So, you just need the equation that defines
your curve. The curve in your jpg appears to be a circle.
y = sqrt(x^2 + r^2) //where r is the radius
That actually yields + or - and you just pick what fits your situation best.
So, you pump in an x and get you 2 y's. Pick the best y and use it.

Subject: [Flashcoders] Curves question for math gurus
Hi,
I have a dynamically drawn curve. It's a simple curve, with 2 end points,
and its yfactor will vary.
I'm trying to figure out a way to have objects "snap" to this curved line.
I
would distribute them over the _x axis, and I need a formula to get their
_y
position on the curved line.
Here is a visual explanation:

Now, I guess this requires trigonometry... And I really am a newb when it
comes to trig...
Any help would be appreciated !
