easeIn(t:Number, b:Number, c:Number, d:Number, s:Number = 0):Number
[static] The easeIn() method starts the motion by backtracking, then reversing direction and moving toward the target.

easeInOut(t:Number, b:Number, c:Number, d:Number, s:Number = 0):Number
[static] The easeInOut() method combines the motion of the easeIn() and easeOut() methods to start the motion by backtracking, then reversing direction and moving toward target, overshooting target slightly, reversing direction again, and then moving back toward the target.
