The mx.effects.easing package contains the easing classes used by effects.

---

	Class	Description
	Back	The Back class defines three easing functions to implement motion with Flex effect classes.
	Bounce	The Bounce class defines three easing functions to implement bounce motion with Flex effect classes.
	Circular	The Circular class defines three easing functions to implement circular motion with Flex effect classes.
	Cubic	The Cubic class defines three easing functions to implement motion with Flex effect classes.
	Elastic	The Elastc class defines three easing functions to implement motion with Flex effect classes, where the motion is defined by an exponentially decaying sine wave.
	Exponential	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.
