In this animation I use the function with domain changing from -0.1..0.1 to -3..3. NOTE, in this example the animation parameter a changes from 0 to 3. This means that the function does not exist in the first keyframe.
The anim09.*.jvx files created by utility xvc2jvx were used as keyframes for JavaView animation. JavaView applet uses default parameters with
<param name=Animation.firstKey value=1>
<param name=Animation.lastKey value=21>
<param name="Animation.framesPerSecond" value=12>
