uTo 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.

uTo 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.

uTo edit an animation

Note: The steps below continue from the procedure under “To trace a locus of points”.

1.While the animation you want to edit is on the display, tap [Edit], [Animate], and then [Edit Animations].

•This displays the animation editing window in the lower window. The upper window contains the animation that we just completed in “To trace a locus of points”.

2.Edit the animation following the procedure below.

Steps:

This setting specifies how many steps point A takes to move along side CD. The initial default value is 20, which can be changed to value from 2 to 100.

Animations:

The “A” under “Animations” indicates that point A is the point moved by the

animation. When you are building multiple animations, a list of all applicable points appears here. Tapping [Remove] deletes the applicable animation.
