Once functions or sequences have been defined in other aplets, they can be referenced in the
e.g. 1 Suppose we use the Function aplet to define
and
F1(X)=X²-2
These functions now become accessible not only from within the
view but also within any other aplet also. This is shown by the screen
shots below.
The results shown will, of course, depend on your settings in the
view.
The reason for the
