Trying to make it matter.
Nice applet. Kind of reminds me of the old Myst game. When I first played with this, I was not sure what the rules were. But I think I can build an absolute value function.
Interesting open ended question.... If the first slider is animated at a constant rate, and the red circles are traced, and we could control the second slider manually, some interesting investigations could be made...Like Steve said, if the second slider is dragged at a constant rate, I'd expect an absolute value function...but if you play with rate and direction of the second slider.... a parabola? ellipse? Lightning Bolt???What have you made with it?
Did you try to match up the open dots with the closed dot?
OHHHHH....matched up the dots...then figured out the red dot could move by a given radius.....Started to look like a hyperbola, but then I was convinced it was a parabola...tried a few educated guesses and realized it seems to build the parabola (1/4)x^2+!So of course the question is, why? Why does it build that?
