[jQuery] easing - only use one function

[jQuery] easing - only use one function


I've removed all functions that I dont't need from the easin-plugin. But when I use it I get an
error. When using all functions, it works as expected.
This is the code I'm using (from the easin plugin):
jQuery.extend({
    easing: {
        bounceout: function(x, t, b, c, d) {
            if ((t/=d) < (1/2.75)) {
                return c*(7.5625*t*t) + b;
            } else if (t < (2/2.75)) {
                return c*(7.5625*(t-=(1.5/2.75))*t + .75) + b;
            } else if (t < (2.5/2.75)) {
                return c*(7.5625*(t-=(2.25/2.75))*t + .9375) + b;
            } else {
                return c*(7.5625*(t-=(2.625/2.75))*t + .984375) + b;
            }
        }
    }
});
What's wrong?
