| Class | public class Quadratic |
Quadratic produces values that would cause a moving subject to move with slow accelleration.
The easing classes provide static methods for interpolating the change between two values over time.
Each class handles the interpolation, or easing, differently. Each class typically contains three methods
- easeIn(), easeOut() and easeInOut() - which vary the rate of change
of the values. Most of the easing functions produce values as a percentage - a number between 0.0 and 1.0

|---|---|---|---|

easeIn(timeElapsed:Number, duration:Number):Number
[static]
easeIn starts out slow and increases in speed towards the end of the duration.
| Quadratic | ||
|
easeInOut(timeElapsed:Number, duration:Number):Number
[static]
easeInOut combines the motion of easeIn and easeOut by starting out slow and increasing in speed
towards the middle of the duration, then slowing down again towards the end.
| Quadratic | ||
|
easeOut(timeElapsed:Number, duration:Number):Number
[static]
easeOut starts out fast and decreases in speed towards the end of the duration.
| Quadratic | ||
|
easeOutIn(timeElapsed:Number, duration:Number):Number
[static]
easeOutIn combines the motion of easeIn and easeOut by starting out decelerating
towards the middle of the duration, then accelerating end.
