u To add an animation and run it
1. Plot a point and draw a figure (here we draw a parallelogram). Or, you could
draw a circle, arc, ellipse, line segment, or function instead of a figure.
2. Select the point and a side of the parallelogram.
3. Tap [Edit], [Animate], and then [Add Animation].
• The point selected in step 2 moves along the side of the parallelogram.
4. Tap [Edit], [Animate], and then [Go (once)], [Go (repeat)], or [Go (to and fro)].
5. Tap [Edit], [Animate], and then [Stop] to stop the animation.
• You can also stop the animation by tapping l on the icon panel.
u To replace the current animation with a new one
1. Select the point and curve for the new animation.
2. Tap [Edit], [Animate], and then [Replace Animation].
• This discards the currently set animation and sets up an animation for a new point and curve set. Tap
[Edit], [Animate], and then [Go (once)] to see your new animation.
u To trace a locus of points
Note:
Using trace leaves a trail of points when the animation is run. The
procedure below is a continuation of the procedure under "To add an
animation and run it".
1. Draw a line segment that connects point A with apex B.
2. Draw the center point of line segment AB.
• Select line segment and then tap [Draw] - [Construct] - [Midpoint].
3. Select the center point of line segment AB (point F) and then tap [Edit] -
[Animate] - [Trace].
4. Tap [Edit], [Animate], and then [Go (once)].
• This draws a line using point F as the locus, that is parallel to and whose
length is half that of side CD of the parallelogram.
