**Section: Types of easing**

GCA has 16 easing equations built in, from purely linear to a quadratic curve to a parabolic bounce. If these don't meet your needs, you can also add your own equations (see below for a few notes on rolling your own).

Most of the included equations are available in three flavors each. “Easing out” describes a sequence in which motion starts out moving rapidly and then slows, more or less gradually, to a stop. “Easing in” is the opposite–-slow to fast. “Easing in-out” combines the two effects. Different functions are used to qualify these three basic categories, resulting in the full names of the easing equations: “quadratic easing in” for example, or “circular easing out”.

Here are the names of the built-in equations:

linear easing (constant speed--the default, not really "eased" at all)

quadratic easing in

quadratic easing out

quadratic easing in-out

cubic easing in

cubic easing out

cubic easing in-out

circular easing in

circular easing out

circular easing in-out

cubic back easing in

cubic back easing out

cubic back easing in-out

bounce easing in

bounce easing out

bounce easing in-out

Again, see the "Eased Movements" example included with the extension to preview each of these effects.
