• All limited warranties on the Software Product are granted only to you and are non-transferable. If you want a larger overshoot, you need to either increase the incoming velocity, or reduce the oscillation frequency.
• See the two sidebar movies for two examples of keyframed animations where the expression provides overshoot. As before, the first two lines just define the variables that control the frequency and decay of the oscillation.
• The bounce-back expression applied to the Position, Rotation, and Scale properties. It is just the opposite of what we wanted.
• When an object bounces, it loses energy on each bounce, which affects both the amplitude and the frequency. It is just the opposite of what we wanted.
