When this message displays, the current figure is not lost. You can
save the figure by:
• Quitting Cabri™ Jr. and deleting some files to create additional
free RAM (5K should be enough). You must not delete the
AppVar CurrCaJ2; it contains the current figure.
• Saving CurrCaJ2 on your computer or another unit and making
use of it later when you have enough available RAM on your
device.
No figure to open! You have selected Open from the F1 menu, but there are no
saved figures on your calculator to open.

Figure abc not re-
archived!
This happens, under tight Flash RAM conditions, when you have
worked with an archived figure and made it significantly larger. In
this case, you may not have enough memory to save the figure in
Flash RAM, so the App saves it as a regular AppVar in RAM.
Batteries too low to
access archived files!
The batteries in your calculator are low, so the App cannot save
the file into Flash RAM . You can save the file without archiving it,
then change the batteries and archive the file later.

Circle A circle is the set of points in a plane whose distance
from a given fixed point in the plane is constant. The
fixed point is the centre of the circle; the constant
distance is the radius.
Ellipse An ellipse is the set of points whose distances from two
fixed points in the plane have a constant sum. The two
fixed points are the foci of the ellipse. The line through
the foci of an ellipse is the ellipse's focal axis. The point
on the axis halfway between the foci is the centre. The
points where the focal axis and ellipse intersect are the
ellipse's vertices.

Using Transformation Graphing App
Transformation Graphing App enhances the ofunction mode and lets you observe the
effects of changing coefficient values without leaving the graph screen. The
transformation feature is only available in function mode (z).
Transformation Graphing allows you to manipulate up to four coefficients on the
graph: A, B, C and D. All other coefficients act like constants, using the value in
memory. You step through the transformation of a function or animate the
transformation using play styles, play/pause, play and fast play. You can enter
functions directly or use the colour/line style spinner dialogue to paste functions such
as:
AX + B
AX2+ B
A(X-B)2+ C
A(X-B)(X-C)
AX2+ BX + C
A(X-B)3+ C
AX3+ BX2+ CX + D
A abs(B(X-C)) + D
A sin(B(X-C)) + D
A cos(B(X-C)) + D
A tan(B(X-C)) + D
