QuinticEase

If you want to add the QuinticEase effect to your easing function, add it to your animation. It accelerates/decelerates using the formula f(t) = t5. You can use PowerEase to create the same by specifying Power="5". Add the following RadioButton to define an animation with the QuinticEase easing function in our StackPanel:

<RadioButton GroupName="AnimationSelector" 
             Content="QuinticEase - EaseInOut" 
             Margin="4"> 
    <RadioButton.Triggers> 
        <EventTrigger RoutedEvent="RadioButton.Checked"> 
            <BeginStoryboard> 
                <Storyboard AutoReverse="True"> 
                    <DoubleAnimation  
                     Storyboard.TargetName="circle" 
                     Storyboard.TargetProperty="(Canvas.Left)" 
                     To="350"> 
                        <DoubleAnimation.EasingFunction>
