Coordinate Transformation
•
This scientific calculator lets you convert between
rectangular coordinates and polar coordinates, i.e., P(

y
)
↔
Rec(

•
Coordinate transformation can be performed in the COMP
and STAT calculation modes.
•
Calculation results

and
r
are stored in variable memory X.
Calculation results
y
and
are stored in variable memory Y.
•
With polar coordinates, can be calculated within a range of
–180º<
≤
180º.
•
If you perform coordinate transformation inside of an
expression instead of a stand alone operation, the
calculation is performed using only the first value (either the
r
-value or the
x
-value) produced by the transformation.
Example: Pol( 2, 2) 5 = 2 5 = 7

•
Although a smaller
tol
value provides better precision, it
causes the calculation to take more time. Specify a
tol
value
that is 1 10
–14
or greater. A default value of 1 10
–5
is used
when you omit specification of the tolerance range.
•
Integration calculations can be performed in the COMP
Mode only.
•
Specify Rad as the calculator’s default angle unit, when
performing
an
integration
calculation
involving
trigonometric functions.
•
Integration calculations can take considerable time to
complete.
•
You cannot input a
tol
value when using Math format.
•
Errors may occur due to the type of function being
integrated, the presence of positive and negative values in
the integration interval, or the interval.

Statistical Calculations
All calculations in this section are performed in the STAT
Mode ( [MODE] [3] ).
Press [MODE] [3] to display
the STAT menu for statistical
calculation type selection.
There are eight types of statistical calculations.
Inputting Sample Data
Once you enter the STAT mode the STAT editor screen appears.
Select a statistical calculation type by pressing the
corresponding number. To display the STAT editor screen from
another STAT mode screen, press [SHIFT] [1] [2].
STAT Editor Screen
There are two STAT editor screen formats, depending on the
type of statistical calculation you selected.
•
The first line of the STAT editor screen shows the value for the
first sample or the values for their first pair samples and the
second line shows the value of second sample and so on.
Frequency Column
A column labeled “FREQ” will also be included on the STAT
editor screen if you turn on the Statistical Display item on the
calculator’s setup screen. You can use the FREQ column to
specify the frequency of each sample value.
Inputting Sample Data
•
Data is inserted into the cell where the cursor is located. Use
the cursor keys to move the cursor between cells.
•
The values and expressions you can input on the STAT editor
screen are the same as those you can input in the COMP
mode with Linear format.
•
Pressing [AC] while inputting data clears your current input.
•
After inputting a value, press [=] to confirm. This registers the
value but the cell can only display a maximum of 6 digits.
Example: To input the value 357 in cell X1, 8 in cell Y1.
[SHIFT] [1] [2]

Editing Sample Data in the STAT Editor Screen
•
Move the cursor to the cell you want to edit, input the new
data or expression then press [=]. Note that you must totally
replace the existing data of the cell with new input. You
cannot edit part of the existing data.
•
To delete a line, move the cursor to the line you want to
delete, press [DEL].
•
To insert a line, move the cursor to the line that will be under
the line you will insert, press [SHIFT] [1] [3] [1]. The insert
operation will not work if the maximum number of lines
allowed for the STAT editor screen are already used.
Deleting All Stat Editor Contents
Press [SHIFT] [1] [3] [2]
•
You can only “insert a line” and “delete all stat editor contents”
when the STAT editor screen is on the display.
Notes
•
The number of lines in STAT editor screen (the number of
sample data values you can input) depends on the type of
statistical data you selected, and on the “STAT” setting of the
calculator’s setup screen.
•
To display the “STAT” setting screen press [SHIFT] [MODE]
[
] [4].
•
The following types of input are not allowed on the STAT
editor screen: [M+] , [SHIFT] [M+] , [SHIFT] [RCL] (i.e. “STO”).
•
When you change to another mode from the STAT mode or
change the Statistical Display Setting (which enable or
disable the FREQ column) on the calculator’s setup screen, all
the sample data you input is deleted automatically.

Pressing the [AC] key returns to the function editor screen.
Function Types that are supported
•
Except for the X variable, other variables (A, B, C, D, Y) and
independent memory (M) are all treated as values (the
current variable assigned to the variable or stored in
independent memory).
• Only
variable X can be used as the variable of a function.
•
An error occur when an End value is less than Start value and
therefore the number table is not generated.
•
Executing a number generation table using a Start, End and
Step value combination that produces more than 30
x
-values
causes an error. To avoid this, the specified Start, End, and
Step values should onlyproduce a maximum of 30
x
-values.
•
Certain functions and Start, End, Step value combinations can
cause number table generation to take a long time.
Number Table Screen
The number table screen shows
x
-values calculated using the
specified Start, End, and Step values, as well as the values
obtained when each
x
-value is substituted in the function
f
(
x
).
•
Table contents cannot be edited. You can use the number
table screen for viewing values only.
•
To returns to the function editor screen, press the [AC] key.
Note that in the Table Mode you should not change the
input/ouput format settings (Math format or Linear
format) otherwise the number table generation function is
cleared.
Scientific Constants
A total of 40 commonly used scientific constants, such as the
speed of light in a vaccum and Planck's constant are built-in for
quick and easy look-up. Simply press [SHIFT] [7] and the
number that corresponds to the scientific constant (see the
table below for a complete list of available constants) you want
to look-up and press [=], it appears instantly on the display.
Example:
Press [SHIFT] [7] [2] [8] [=]
Metric Conversion

quick and easy conversion to and from metric units. For details,
please refer to the following table.

Trouble Shooting
Perform the following steps whenever an error occurs during a
calculation or when calculation results are not what you
expected. If one step does not correct the problem, move on to
the next step.
Note that you should make separate copies of important data
before performing these steps.
•
Check the calculation expression to make sure that it does
not contain any errors.
•
Make sure that you are using the correct mode for the type of
calculation you are trying to perform.
•
If the above steps do not correct your problem, press the
[ON] key. This will cause the calculator to perform a routine
that checks whether calculation functions are operating
correctly. If the calculator discovers any abnormality, it
automatically initializes the calculation mode and clears
memory contents.

Initialize all modes and settings by performing the following
operation:

Vector Calculations
Press [MODE] [8] to select the VECTOR MODE. You can save
vectors under the names “VctA”, “VctB”, “VctC” in vector
memory. Vector calculation results are stored in a special
Vector Answer Memory named “VctAns”.
•
In the VECTOR mode,
press [SHIFT] [5] [1] to
display the vector selection
screen.
Note that the vector selection screen also appears whenever
you enter the VECTOR mode.
•
Press [1], [2] or [3] to specify
the name of the vector you
want to select. This display
a screen for configuring
dimension settings. Press the corresponding number to
specify the vector dimension you want to use and the vector
editor screen appears.
•
Use the vector editor screen to input each of the elements.
•
If you want to create another vector, repeat the above
procedure.
•
You can copy the contents of one vector to another using
the same procedure as described in the Matrix section.
•
The following are the menu items on the vector menu that
appears when you press [SHIFT] [5].
Example: Input VctA = (1, 2) and VctB = (3, 4)
To input VctA press [MODE] [8] [1] [2]
then press [1] [=] [2] [=]
To input VctB press [AC] [SHIFT] [5] [1] [2] [2]
then press [3] [=] [4] [=]
