Reading the Display The display of the calculator shows expressions you input, calculation results, and various indicators. Input expression Indicators Math Math Calculation result • If a ' indicator appears on the right side of the calculation result, it means the displayed calculation result continues to the right. Use e and d to scroll the calculation result display. • If a g indicator appears on the right side of the input expression, it means the displayed calculation continues to the right.
Disp The display currently shows an intermediate result of a multi-statement calculation. Important: For some type of calculation that takes a long time to execute, the display may show only the above indicators (without any value) while it performs the calculation internally. Using Menus Some of the calculator’s operations are performed using menus. Pressing N or w, for example, will display a menu of applicable functions. The following are the operations you should use to navigate between menus.
Note: • The calculator switches to Linear Display automatically whenever you enter the STAT, BASE-N, or VECTOR Mode. • In this manual, the B symbol next to a sample operation indicates Natural Display (LineO), while the b symbol indicates Linear Display. 3Deg 4Rad 5Gra Specifies degrees, radians or grads as the angle unit for value input and calculation result display. Note: In this manual, the v symbol next to a sample operation indicates degrees, while the V symbol indicates radians.
Inputting Expressions and Values Basic Input Rules Calculations can be input in the same form as they are written. When you press = the priority sequence of the input calculation will be evaluated automatically and the result will appear on the display. 4 × sin30 × (30 + 10 × 3) = 120 4 *s 30 )*( 30 + 10 * 3 )= 2 * *1 Math *3 *1 Input of the closing parenthesis is required for sin, sinh, and other functions that include parentheses. *2 These multiplication symbols (×) can be omitted.
sin(30) × 4 :B 5 ' 4 c 5 dddds 30 ) Math Math = Note: • If the calculation becomes longer than the screen width during input, the screen will scroll automatically to the right and the ] indicator will appear on the display. When this happens, you can scroll back to the left by using d and e to move the cursor. • When Linear Display is selected, pressing f will cause the cursor to jump to the beginning of the calculation, while c will jump to the end.
Inputting with Natural Display Selecting Natural Display makes it possible to input and display fractions and certain functions (x2, x3, x^, ), #, ", x−1, 10^, e^, Abs) just as they are written in your textbook. 2+' 2 1+' 2 B Math ' 2 +! 2 ee 1 +! 2 = Important: • Certain types of expressions can cause the height of a calculation formula to be greater than one display line. The maximum allowable height of a calculation formula is two display screens (31 dots × 2).
Overwrite Input Mode (Linear Display only) You can select either insert or overwrite as the input mode, but only while Linear Display is selected. In the overwrite mode, text you input replaces the text at the current cursor location. You can toggle between the insert and overwrite modes by performing the operations: 1Y(INS). The cursor appears as “I” in the insert mode and as “ ” in the overwrite mode.
