Quick Reference to Keys (Continued) A Key %  % k % d > % Z % t Function Displays the RESET menu. RESET: N Y Press < when N (no) is underlined to return to the previous screen without resetting the calculator. Press < when Y (yes) is underlined to reset the calculator. The message MEM CLEARED is displayed. Also, press & and - simultaneously to reset the calculator immediately. No menu or message is displayed. Displays the following menu that lets you convert rectangular coordinates (c,y) to polar coordinates (r,q) or vice versa. R4Pr Converts rectangular coordinate to polar coordinate r. R4Pq Converts rectangular coordinate to polar coordinate q. P4Rc Converts polar coordinate to rectangular coordinate c. P4Ry Converts polar coordinate to rectangular coordinate y. Displays the following numeric notation mode menu. FLO Restores standard mode (floating decimal). SCI Turns on scientific mode and displays results as a number from 1 to 10 (1  n < 10) times 10 to an integer power. ENG Turns on engineering mode and displays results as a number from 1 to 1000 (1  n < 1000) times 10 to an integer power. The integer power is always a multiple of 3. Calculates the sine. Calculates the inverse sine. Displays the following menu from which you can select 1-VAR, 2-VAR, or CLRDATA. 1-VAR 2-VAR CLRDATA Analyzes data from 1 set of data with 1 measured variable-x. Analyzes paired data from 2 sets of data with 2 measured variables-x, the independent variable, and y, the dependent variable. Clears data values without exiting STAT mode. © 1999 TEXAS INSTRUMENTS INCORPORATED TI-30X ÙS: A Guide For Teachers A-4
