each axis, as well as their scales (distance between
hash marks). Before drawing a graph, you should first
specify range parameters to set the size of the graph.
• Range parameter types
Range parameters consist of the following:
•Specifying range parameters
Whenever you press the key (except in the BASE-N
mode), the range parameter setting screen appears on the
display. Enter the value you want to specify for the
displayed parameter and then press .
Change the range parameters on the left to
those on the right.
the range of the first graph. The first graph is produced
by using the previously mentioned operation ( function
key] ).
Subsequent graphs are produced using the
variable X in the operation [function key]
By inputting after the function key, the range is
unchanged and the next graph is produced without clearing
the existing display.
Overdraw the graph for y=cos x on the graph for
y=sin x.
First, draw the graph for y=sin x.
(Note)
Built-in function graphs cannot be used in multistatements
and cannot be written into programs.
Built-in function graphs can also be used in combination
with each other. Graphing a formula such as y=2x
2 + 3x -5
makes it possible to visually represent the solution.
Unlike built-in functions, the ranges of user generated
graphs are not set automatically, so graphs produced
outside of the display range do not appear on the display.
Range parameters
After pressing the key, you can look up and specify
the range parameters for the x- and y- coordinates. Range
parameters consist of maximum and minimum values for
