Actionscript:

var a:Number = 200;
-
x = stage.stageWidth / 2;
-
y = stage.stageHeight / 2;
-
-
graphics.lineStyle(0,0x000000);
-

-
function onRun(evt:Event):void {
-
xp = a * Math.cos(t) - (a * Math.pow(Math.sin(t),2))/Math.sqrt(2);
-
yp = a * Math.cos(t) * Math.sin(t);
-
if (t == 0){
-
graphics.moveTo(xp, yp);
