Once functions or sequences have been defined in other aplets, they can be
referenced in the HOME view.
e.g. 1 Suppose we use the Function aplet to
define F1(X)=X²-2 and
F2(X)=e^X as shown right.
These functions now become accessible not only from within the HOME 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 MODES view.
The reason for the QUOTE(X-2) rather than
just X-2, is that using X-2 would tell the
calculator to use the value currently stored in
memory X, while QUOTE(X-2) tells it to use
the symbol. The QUOTE function is available
through the MATH menu under Symbolic (see
page 257).
This type of work is actually far more easily done in the Function aplet, where
QUOTE is not needed and the
key does a better job. See page 71.
e.g. 2 Suppose we use the Sequence aplet
to define a sequence with
12
3, 1TT==and
12
2
nnn
TTT

=+.
In the HOME view, the sequence values can be
referred to as easily as the function values in
the previous example.
