User manual TEXAS INSTRUMENTS TI-34II EXPLORER PLUS QUICK REFERENCE GUIDE

[. . . ] Order of Operations Fractions TI. 34 Explorer Plus Scientific Calculator Copyright 1999 Texas Instruments The TI-34 uses EOS (Equation Operating System) to evaluate expressions. 2nd Functions that need a ) and precede the argument, such as the sin, log, and all RP menu items. 4th Functions that are entered after the argument, such as x 2 and angle unit modifiers ( r). 7th Permutations (nPr) and combinations (nCr). [. . . ] Ans is retained in memory, even after the TI-34 is turned off. To recall the value of Ans: Press % i (Ans displays on the screen), or Press any operations key (T, U, F, etc. ) as the first part of an entry. Ans and the operator are both displayed. % Y divides 2 positive integers and displays the quotient, Q, and the remainder, R. Only the quotient is stored to Ans. % B displays a menu of all trigonometric functions (sin, sin -1, cos, cos-1, tan, tan-1). Select the trigonometric function from the menu and then enter the value. Set the desired Angle mode before starting trigonometric calculations. % A displays a menu of all log functions (log, 10^, ln, e ^). Select the log function from the menu, then enter the value, and complete it with E <. RectangularPolar %k % k displays a menu to convert rectangular coordinates (x, y) to polar coordinates (r, ) or vice versa. Set Angle mode, as necessary, before starting calculations. US 34IIOM1L1A Page 1 Stored Operations m o % n p The TI-34 stores two operations, OP1 and OP2. To store an operation to OP1 or OP2 and recall it: 1. Enter the operation (any combination of numbers, operators, or menu items and their arguments). Press < to save the operation to memory. m or o recalls and displays the operation on the entry line. The TI-34 automatically calculates the result (without pressing <) and displays the counter (as space permits) on the left side of the result line. You can set the TI-34 to display only the counter and the result (excluding the entry). until the = is highlighted () and press <. Repeat to toggle this setting off. Stats %t w v u Errors ARGUMENT -- A function does not have the correct number 1-VAR stats analyzes data from 1 data set with 1 measured variable, X. 2-VAR stats analyzes paired data from 2 data sets with 2 measured variables-- X, the independent variable, and Y, the dependent variable. Steps for defining statistical data points: 1. Then: of arguments. DIVIDE BY 0 -- You attempted to divide by 0. DOMAIN -- You specified an argument to a function outside In 1-VAR stat mode, enter the frequency of occurrence (FRQ) of the data point and press $. Or In 2-VAR stat mode, enter the value for Y 1 and press $. Memory z L % h{ The TI-34 has 5 memory variables--A, B, C, D, and E.
