to access. The following 7 sub-menu tools are
available:
1 Value
With this sub-menu tool, the Y value can be obtained
by entering an X value. The flashing graph cursor will
then be placed in that position on the graph. If more
than one graph equation is set, use the
{
or
}
keys to switch to the equation you wish to work
with.
Note:
If the entered X value is
incalculable, an error
message will be displayed.
Also, if the Y value exceeds
the calculation range, then “-
---” will be displayed instead.
2 Intsct
With this tool, the intersection(s) of two or more graphs
can be found, where the flashing cursor will be placed.
When the intersection is found, then the X-Y coordi-
nates of the intersection will be displayed at the bottom
of the screen. If there is more than one intersection,
the next intersection(s) can be found by selecting the
tool again.
Note:
If there is only one graph
equation entered there will
be no other graph(s) to form
an intersection, so selecting
this tool will result in an
error.
3 Minimum
Finds the minimum of the given graph, and places the
flashing cursor at that position.
Note:
If the given graph has no
minimum value, an error
message will be displayed.
