x = r * sinA / (1 - sinA)
(Math teachers told my daughter yesterday she'd need sin and cos someday
so she came home and made me give her three examples of how/why I've
used it with flash -- if anyone has any good ones besides eyes following
mouse, moving object on a line relative to horizon,
Hi List,
I'm trying to figure out what radius to make n number of circles fit
around a circle of radius r. Several diagrams later I'd got it down to:
sinA = x / (x + r)
Where A is half the angle required by each circle ((360/n)/2), x is the
radius we're looking for and r is the radius of th
2 matches
