This calculator has a total of 20 pre-elaborated graphs, mak-
ing it possible for you to produce basic function graphs.
Graphing over pre-elaborated graphs
Two or more pre-elaborated graphs can be displayed on the
same screen. The range of the fi rst graph is automatically
adjusted and the following graphs will be adjusted to this
range.
The fi rst graph is elaborated using the method previously
explained ( + function + )
The following graphs are elaborated using the x variable in
the operation (function key)
If you press the button after the function key, the
range will not change and the next graph will be produced
without deleting the existing graph.
Example:
Trace the graph y=cos x on top of the graph y=sin x
