The Exponential class defines three easing functions to implement
motion with Flex effect classes, where the motion is defined by
an exponentially decaying sine wave.

public static function easeIn(t:Number, b:Number, c:Number, d:Number, ... rest):Number
The easeIn()
method starts motion slowly,
and then accelerates motion as it executes.
Parameters
 t:Number — Specifies time.


 b:Number — Specifies the initial position of a component.


 c:Number — Specifies the total change in position of the component.


 d:Number — Specifies the duration of the effect, in milliseconds.


 ... rest 
Returns
 Number — Number corresponding to the position of the component.

public static function easeInOut(t:Number, b:Number, c:Number, d:Number, ... rest):Number
The easeInOut()
method combines the motion
of the easeIn()
and easeOut()
methods
to start the motion slowly, accelerate motion, then decelerate.
Parameters
 t:Number — Specifies time.


 b:Number — Specifies the initial position of a component.


 c:Number — Specifies the total change in position of the component.


 d:Number — Specifies the duration of the effect, in milliseconds.


 ... rest 
Returns
 Number — Number corresponding to the position of the component.

public static function easeOut(t:Number, b:Number, c:Number, d:Number, ... rest):Number
The easeOut()
method starts motion fast,
and then decelerates motion as it executes.
Parameters
 t:Number — Specifies time.


 b:Number — Specifies the initial position of a component.


 c:Number — Specifies the total change in position of the component.


 d:Number — Specifies the duration of the effect, in milliseconds.


 ... rest 
Returns
 Number — Number corresponding to the position of the component.
