The Sine class defines easing functionality using a Sine function. Easing consists of two phases: the acceleration, or ease in phase, followed by the deceleration, or ease out phase. Use the easeInFraction property to specify the percentage of an animation accelerating.

Sine()Constructor
public function Sine(easeInFraction:Number = 0.5)

Language Version : ActionScript 3.0
Product Version : Flex 4
Runtime Versions : Flash Player 10, AIR 1.5

Constructor.

Parameters
easeInFraction:Number (default = 0.5) — Sets the value of the easeInFraction property. The default value is EasingFraction.IN_OUT, which eases in for the first half of the time and eases out for the remainder.
