Simple
explanation (how to use)
To
draw graphs
1
We choose the form of the graph that we want to
draw in
the "graph" menu.
2
We input only expressions coming out in front
of or behind equality (=) in the form.
At
this time, only characters such as variables to be used, function keys, number
keys, point, operation keys are inputted.
(But
other figures: using commands, we can use all keys.)
3
Before we select the "Draw graphs; Perforn
calculation" menu (icon button), we confirm and adjust conditions
of the time when the graph
is drawn.
4
Then, we select the "Draw graphs; Perforn
calculation" menu (icon button). (or we
press "Enter".)
The
following items we have to adjust was decided
basically adequately.
The
conditions that we have to confirm and adjust are like the
followings.
Angle
unit of trigonometric function (selecting one between
Deg and Rad)
Coordinates
range where a graph will be drawn, and domain
Space
frame direction in 3dimensional screen
Drawing
method of surfaces or curves
Additively
a
graph
is drawn according to the following additive conditions.
Width,
length of the drawing screen
Region
of plane coordinates
Restricted
region where a graph will be drawn within the coordinates
range
Increment
of variable values of a domain or Equaldivision of
interval
Color
and thickness of a graph, thickness of a axis and
the space
frame, kind of a line, background color
Thickness
and size of a coordinates scale, To display coordinates
values, To display the origin and the name of coordinates
axis, shape of and arrowhead of coordinates axis
In
a 2dimensional screen  section paper, to display
coordinates axis, no display
In
a 3dimensional screen  to display a space frame
and a space axis, kind of a space frame
Subdivision
of "command figures" related with figures
Shape
and color of cubic surfaces, illumination
If last coordinates range is not changed, this program draws a
graph on it
If
last coordinates range is changed in comparision with the
front,
this program erases the existing graph, and draws
a graph newly.
If
you want to erase the existing graph and draw in new
condition, you select the “Erase
the drawing screen” menu (icon button).
To
calculate integral, function, etc.
1
We choose the kind we want to calculate in the
"calculation"
menu.
2
We input expressions to calculate.
At
this time, only characters such as variables to be used, function keys, number
keys, point, operation key are inputted.
3
Then, we select the "Draw graphs; Perforn
calculation" menu (icon button). (or we
press "Enter".)
To
calculate matrix
1
We choose matrix calculation in the "calculation" menu.
2
In the form of presented matrix calculation,
we
select the row and the column of matrix and input elements
of
matrix in the text box.
(We
input rows classifying by line, columns by
spaces. Fractions (ex: 2/3
etc.) can also be inputted.)
3
We select the "input finish" button.
4
We select the button to calculate. ( sum and difference and
product of matrix, inverse matrix and so on).
To
use statistic analysis
1
We choose statistic analysis in the "calculation" menu.
2
In statistic analysis form,
a. We
choose the input form of data in the menu.
b. We
choose one among 1variable sample, 2variables sample, 3variables sample, "analysis C use."
In
1variable sample, we do not use parenthesis.
In
2variables sample, 3variables sample, we use the method
to tie data by parenthesis like (x, y) or (x, y, z).
In 'analysis
C use,' we do not use parenthesis and input data by
using
space in one row like
x y z.
(It
recognizes variables up to 20variables and calculates.)
c. After
inputting data, we select the "input finish"
option.
d. We
choose one of the next two buttons to notice whether
we classify data by classclassification or
by
apiececlassification.
e. If
selecting classclassification, we select the "class
interval when classifying classclassification" menu
and
decide
class intervals by using the loaded dialogue box.
If
analyzing or drawing graphs,
f. we select the "graphs, form" menu
in the "Form" menu
and choose contents to analyze or the kind of the graph to draw.
g. We
select the "Analysis" button. If drawing a
graph, we
select the "graph" button.
(A
graph
is drawn in the drawing screen.)
If we
want to
make a frequency table,
We select the "frequency table..." menu
in the "Form"
menu and choose the frequency to represent.
And
we select the "frequency table" button.
If
obtaining special result, we select the "special
result" button after checking what we want to pbtain in the 'group to
calculate and special result...' menu.
