This setting specifies how many times the animation should be executed when you select T > [Animate]
> [Go(repeat)]. The initial default value is 10, which can be changed to a value from 0 to 20. Inputting 0
here causes the animation to repeat until you press b or a to stop it.
• Steps:
This setting specifies how many steps point E takes to move line segment AB. The initial default value is
20, which can be changed to a value from 2 to 100.
• Animations:
The "E" under "Animations" indicates that point E is the point moved by the animation. When you are
building multiple animations, a list of all applicable points appears here. Selecting T > [Delete] while
a letter is highlighted deletes the applicable animation. Selecting T > [Delete] while "Animations" is
highlighted deletes all the animations.
"t0" and "t1" specify the range of movement of point E on line segment AB. The initial default values are t0
= 0 and t1 = 1. During animation, the length of AB is considered to be one unit. The default values specify
that movement of point E is from start point A (point where length equals 0) up to end point B (point where
length equals 1). You can input a number from -10 to 10 for t0 and t1.
Changing the value of t0 to 0.5 causes point E to move from the middle of line segment AB to point B.
Changing the value of t0 to -1 causes point E to begin at a point outside line segment AB (in this case, the
distance from point A to point E equals the length of line AB) and end with point B. Changing the values
to t0 = 1, t1 = 0 causes point E to move from point B to point A.
• Traces:
This item shows the specified trace point. Selecting T > [Delete] while a letter is highlighted cancels the
applicable trace point setting. Selecting T > [Delete] while "Traces" is highlighted cancels all the trace
point settings.
3. After all the settings are the way you want, press b.
Generating an Animation Table
Under default settings, an animation causes a specified point to move along a specified line segment, circle,
arc, or function in 20 steps. You can configure the calculator to generate a table, called an "animation table",
which records the coordinates of each step, the length of the line segment, the area of the object, etc.
Any of the following data can be added to the animation table: coordinates ( x , y ), distance/length, slope, radius,
circumference, perimeter, area, angle, supplementary angle, vector segments ( x , y ), and expression.
You can also select a single column of the animation table and save it as a list, or save the entire animation table
as spreadsheet data. The saved data can then be used for analysis with the Statistics app or the Spreadsheet
app.
To add columns to the animation table
The steps below continue from the procedure of Example 2 under
First, the coordinates of point F are added to the animation table. Then the angles of line segments EC and
AB connecting point E and point C are added to the animation table.
1. Here we will generate an animation table for the coordinates ( x , y ) of point F, so first select point F.
2. Press V to display the measurement box.
• If the (coordinates) icon does not appear on the left
edge of the screen, highlight the up arrow to the left of the
measurement box and then press O. On the icon palette
that appears, select the
3. Use r to highlight the up arrow button on the right side of the measurement box and then press O.
4. On the menu that appears, select [Add Table] and then press O.
