User manual TEXAS INSTRUMENTS TI-30X IIB

[. . . ] Last Answer %i TI-30X B and TI-30X S Scientific Calculators 1999 Texas Instruments Incorporated The most recently calculated result is stored to the variable Ans. Ans is retained in memory, even after the TI-30X 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. Select a unit modifier ( ) for any part of an entry. [. . . ] You can store a real number or an expression that results in a real number to a memory variable. % { clears all variable values. Notation %, %d %C Pi g p=3. 141592653590 for calculations. p=3. 141592654 for display. Angle Modes I= Previous Entries #$ After an expression is evaluated, use # and $ to scroll through previous entries, which are stored in the TI-30X memory. You cannot retrieve previous entries while in STAT mode. You can edit a previous entry and press < to evaluate the new expression. I displays a menu to specify the Angle mode as degrees, radians, or gradients. = displays a menu to specify the Angle unit modifier-- degrees (), radians ( r), gradients (g), or DMS ( ). It also lets you convert an angle to DMS Notation (4DMS). To set the Angle mode for any part of an entry: Select the Angle mode. Entries are interpreted and results displayed according to the Angle mode, or % , displays the Decimal Notation mode menu. These modes affect only the display of results. F (default) restores standard notation (floating-decimal) format. 0123456789 sets decimal places to n (09), retaining numeric notation mode format. % d displays the Numeric Notation mode menu. These modes affect only the display of results. FLO (default): Floating Notation, with digits to the left and right of the decimal SCI: Scientific Notation ENG: Engineering Notation (exponent is a multiple of 3) % C enters a value in Scientific Notation, regardless of the numeric notation mode. Press M before entering a negative exponent. ENG 30XOM1L1/A Page 1 Statistics %tw v u 1-VAR analyzes statistical 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. In 1-VAR stat mode, enter the frequency of occurrence (FRQ) of the data point. In 2-VAR stat mode, enter the value for Y1 and press <.
