Example: 2 . (5 + 4) – 2 . (–3) = 2*(5+4)-2 22. .. ( (( 5 55+ ++ 4 44 ) )) – –– 2 22. .. - --3 33 2*-3w 24 2424 A Inputting Scientific Functions with Parentheses (sin, cos, ', etc.) Your calculator supports input of the scientific functions with parentheses shown below. Note that after you input the argument, you need to press ) to close the parentheses. sin(, cos(, tan(, sin–1(, cos–1(, tan–1(, sinh(, cosh(, tanh(, sinh–1(, cosh–1(, tanh–1(, log(, ln(, e^(, 10^(, '(, 3'(, Abs(, Pol(, Rec(, arg(, Conjg(, Not(, Neg(, Rnd( Example: sin 30 = s30)w si sisi n nn ( (( 30 3030 ) )) 05 0505 E-10 A Omitting the Multiplication Sign You can omit the multiplication sign in the following cases. • Immediately before an open parenthesis: 2 . (5 + 4) • Immediately before a scientific function with parentheses: 2 . sin(30), 2 . '(3) • Before a prefix symbol (excluding the minus sign): 2 . h123 • Before a variable name, constant, or random number: 20 . A, 2 . ., 2 . i A Final Closed Parenthesis You can omit one or more closed parentheses that come at the end of a calculation, immediately before the w key is pressed. Example: (2 + 3) . (4 – 1) = 15 (2+3)* ( (( 2 22+ ++3 33) )). .. ( ((4 44– ––1 11 (4-1w 15 1515 • Simply press w without closing the parentheses. The above applies to the closing parentheses at the end of the calculation only. Your calculation will not produce the correct result if you forget the closing parentheses that are required before the end. A Scrolling the Screen Left and Right Inputting a mathematical expression that has more than 16 characters in it will cause the screen to scroll automatically, causing part of the expression to move off of the display. The “b” symbol on the left edge of the screen indicates that there is additional data off the left side of the display. Input Expression 12345 + 12345 + 12345 Displayed Expression 34 34345 55+ ++1 11234 2342345 55+ ++12 12123 334 445 55I II Cursor • While the b symbol is on the screen, you can use the d key to move the cursor to the left and scroll the screen. • Scrolling to the left causes part of the expression to run off the right side of the display, which is indicated by the \ symbol on the right. While the \ symbol is on the screen, you can use the e key to move the cursor to the right and scroll the screen. • You can also press f to jump to the beginning of the expression, or c to jump to the end. A Number of Input Characters (Bytes) As you input a mathematical expression, it is stored in memory called an “input area,” which has a capacity of 99 bytes. This means you can input up to 99 bytes for a single mathematical expression. Normally, the cursor that indicates the current input location on the display is either a flashing vertical bar (|) or horizontal bar ( ). When the remaining capacity of the input area is eight bytes or less, the cursor changes to a flashing box (k). If this happens, stop input of the current expression at some suitable location and calculate its result. E-11 k Editing a Calculation A Insert Mode and Overwrite Mode The calculator has two input modes. The insert mode inserts your input at the cursor location, shifting anything to the right of the cursor to make room. The overwrite mode replaces the key operation at the cursor location with your input. Original Expression Pressing + Insert Mode 1+2|34 Cursor 1+2+|34 Overwrite Mode 1+2 3 4 Cursor 1+2 + 4 A vertical cursor (|) indicates the insert mode, while a horizontal cursor ( ) indicates the overwrite mode. Selecting an Input Mode The initial default input mode setting is insert mode. To change to the overwrite mode, press: 1D(INS). A Editing a Key Operation You Just Input When the cursor is located at the end of the input, press D to delete the last key operation you performed. Example: To correct 369 . 13 so it becomes 369 . 12 369*13 D 2 369 369369 . .. 13 1313 I II 369 369369 . .. 1I 1I1I 369 369369 . .. 12 1212 I II A Deleting a Key Operation With the insert mode, use d and e to move the cursor to the right of the key operation you want to delete and then press D. With the overwrite mode, move the cursor to the key operation you want to delete and then press D. Each press of D deletes one key operation. Example: To correct 369 . . 12 so it becomes 369 . 12 Insert Mode 369**12 dd D Overwrite Mode 369**12 369 369369 .. .... 12 1212 I II 369 369369 .. .... I1 I1I1 2 22 369 369369 . ..

With the overwrite mode, move the cursor to the key operation you want to correct and then perform the correct key operation. Example: To correct cos(60) so it becomes sin(60) Insert Mode c60) dddD s Overwrite Mode c60) dddd s A Inserting Key Operations into an Expression Be sure ...
