PowerEase

It defines an easing function that creates an animation that accelerates/decelerates using the formula f(t) = tp, where p is equal to the value of the Power property. As with other easing functions, you can add an easing mode to specify whether the animation will accelerate or decelerate.

In this demonstration, add the following RadioButton that defines the PowerEase easing function to the DoubleAnimation specified:

<RadioButton GroupName="AnimationSelector" 
             Content="PowerEase - EaseInOut" 
             Margin="4"> 
    <RadioButton.Triggers> 
        <EventTrigger RoutedEvent="RadioButton.Checked"> 
            <BeginStoryboard> 
                <Storyboard AutoReverse="True"> 
                    <DoubleAnimation  
                     Storyboard.TargetName="circle" 
                     Storyboard.TargetProperty="(Canvas.Left)" 
                     To=&quot...
