Entering, Displaying, And Editing The Equation - Sharp WriteView EL-W506 Operation Manual

SET UP Menu
Press @ J to display the
SET UP menu.
Press j to exit the SET UP menu.
Determination of the angular unit
The following three angular units (degrees, radians, and grads)
can be specifi ed.
@ J 0 0 (default)
DEG (°):
RAD (rad): @ J 0 1
GRAD (g): @ J 0 2
Selecting the display notation and decimal places
Five display notation systems are used to display calculation
results: Two settings of Floating point (NORM1 and NORM2),
Fixed decimal point (FIX), Scientifi c notation (SCI), and
Engineering notation (ENG).
• When @ J 1 0 (FIX) or @ J 1 2
(ENG) is pressed, "TAB(0–9)?" will be displayed and the number
of decimal places (TAB) can be set to any value between 0 and 9.
• When @ J 1 1 (SCI) is pressed, "SIG(0–9)?" will
be displayed and the number of signifi cant digits can be set to
any value between 0 and 9. Entering 0 will set a 10-digit display.
Setting the fl oating point number system in scientifi c notation
Two settings are used to display a fl oating-point number: NORM1
(the default) and NORM2. A number is automatically displayed in
scientifi c notation outside a preset range:
• NORM1 (@ J 1 3): 0.000000001 | x | 9,999,999,999
• NORM2 (@ J 1 4): 0.01 | x | 9,999,999,999
Selecting the editor
Two editors are available in NORMAL mode:
• The WriteView editor (W-VIEW): @ J 2 0 (default)
• The Line editor (LINE): @ J 2 1
Note: Any entries will be cleared when you change the editor.
Adjusting the display contrast
Press @ J 3, then + or & to adjust the contrast.
Press j to exit.
Insert and overwrite entry methods
When using the Line editor, you can change the entry method
from "INSERT" (the default) to "OVERWRITE".
After you switch to the overwrite method (by pressing @ J
4 1), the triangular cursor will change to a rectangular
one, and the number or function underneath it will be overwritten
as you make entries.
Name display function
You can save a username in this calculator. When you turn the
power off, the saved username is displayed momentarily.
Up to 32 characters may be saved, split over two lines.
Entering and editing the username:
1. Press @ J 5. The
editing screen appears with a
fl ashing cursor.
2. Use u and d to scroll
through the available characters. The following characters
can be entered (listed in the order that they appear):
Letters (A to Z, uppercase only), numbers (0 to 9), slash (/),
hyphen (-), colon (:), apostrophe ('), comma (,), period (.),
and space ( ).
Press @ u to jump to "A", and press @ d or
j to jump to the space.
3. Pressing l or r moves the cursor to the left or right.
To modify a character, use l or r to move the
cursor to the character, then select another character using
u or d.
Press @ l or @ r to jump to the beginning of
the fi rst line or the end of the second.
4. Repeat steps 2 and 3 above to continue entering characters.
5. Press = to save.
Note: Press @ Z in the editing screen to clear all the
characters.

ENTERING, DISPLAYING, AND EDITING THE EQUATION

The WriteView Editor
Entry and display
In the WriteView editor, you can
enter and display fractions or certain
functions as you would write them.
Notes:
• The WriteView editor can only be used in NORMAL mode.
• If the equation grows too large, it may extend off the edge of the
display after you obtain the result. If you want to see the entire
equation, press l or r to return to the editing screen.
Displaying calculation results
When possible, calculation results will be displayed using
fractions, r, and
cycle through the following display styles:
• Mixed fractions (with or without
(with or without
1
• Proper fractions (with or without
• Irrational numbers (square roots, fractions made using
square roots)
Notes:
• In the following cases, calculation results may be displayed
using r:
• Arithmetic operations and memory calculations
• Trigonometric calculations
• In trigonometric calculations,
when entering values such as
those in the table to the right,
results may be shown using r.
• Calculation results may extend
off the edges of the screen. You can see those parts by
pressing l or r (depending on whether the left or
right portion is hidden).
• Improper/proper fractions will be converted to and displayed
as decimal numbers if the number of digits used in their
expression is greater than nine. In the case of mixed
fractions, the maximum number of displayable digits
(including integers) is eight.
• If the number of digits in the denominator of a fractional
result that uses
converted to and displayed as a decimal number.
The Line Editor
Entry and display
In the Line editor, you can enter
and display equations line by line.
Notes:
• Up to three lines of text may be
viewed on the screen at one time.
• If the length of the equation exceeds three lines, parts of it
may be hidden from view after calculation. If you want to see
the rest of the equation, press l or r to return to the
editing screen.
• In the Line editor, calculation results are displayed in
decimal form or line fraction notation if possible.
Editing the Equation
Just after obtaining an answer, pressing l brings you to
the end of the equation and pressing r brings you to the
beginning. Press l, r, u, or d to move the
cursor. Press @ l or @ r to jump the cursor to
the beginning or the end of the equation.
In the WriteView editor, you can use u and d to
move the cursor up and down—between the numerator and
denominator, for example.
Back space and delete key
To delete a number or function, move the cursor to the right of
it, then press N. You can also delete a number or function
that the cursor is directly over by pressing @ y.
The MATH Menu
Other functions may be available on this calculator besides
those printed on the key pad. These functions are accessed
using the MATH menu. The MATH menu has different contents
for each mode.
Press N to display the MATH
menu. For example, in NORMAL
mode, you can call the functions
shown on the right.
