Imagine either of these two scenarios….
(i) you are a student and you have filled the Function aplet with a set of
equations needed for tonight’s homework and set up the PLOT screen
so that it looks exactly the way you want it to. Now you find that you
need the Function aplet to do something else equally important which
will mean wiping all that work.
(ii) you are a teacher and you are planning a lesson where you will
examine a collection of about half a dozen data sets and graph the
results. You don’t want to spend half the lesson waiting while the
students type the data into the Statistics aplet and then watch while
they all use different axes and get totally different graphs.
In either of those two cases, the solution is to make a copy of the aplet
concerned. You can make as many copies of any of the standard aplets as
you wish, with the only limit being the calculator’s memory.
Let’s look at each of the two scenarios in turn.
Copying and adding to the Function aplet
In the first case, what the student needs to do is to make a copy of the
Function aplet to hold his homework (the functions he had already set up)
and then do the unexpected extra work in the original Function aplet which is
now free.
Press the APLET key to see the list of aplets.
Move the highlight to Function (or whichever
one you wish to copy) and press the screen
key labeled .
You will now be asked to nominate a name for
the newly created aplet. It is a good idea to
name it something that will remind you of its
purpose and contents later. After all, you may
end up saving it permanently onto a PC or Mac
using the Connectivity Kit and when you look
at it six months from now a name of
“Homework” is not going to tell you much. Your
name can contain spaces and any other
characters, including those from the CHARS menu.
