Quick Reference to Keys (Continued) A KEY % _ % [,] % c N % O % i % { ? % [ v J I % ^ % C < FUNCTION Changes a real number to percent. Results display according to the decimal notation mode setting. Enters a comma. Calculates the specified root (x) of the value. Lets you enter mixed numbers and fractions. Converts a simple fraction to a mixed number or a mixed number to a simple fraction. Recalls the most recently calculated result, displaying it as Ans. Clears characters and error messages on the entry line. Once the display is clear, it moves the cursor to the last entry in history. Clears all memory variables. Calculates the cosine. Calculates the inverse cosine. Lets you enter the statistical data points (x for 1-VAR stats; x and y for 2-VAR stats). Deletes the character at the cursor. If you hold J down, it deletes all characters to the right. Then each time you press J, it deletes 1 character to the left of the cursor. Displays the following menu that lets you change the Angle mode to degrees (º), radians (r), or gradients (g), and then back to degrees without affecting the value in the display. DEG Sets degree mode. RAD Sets radian mode. GRD Sets gradient mode. When you turn on the TI30X ÙS, it is always in the DEG mode. Calculates the natural antilogarithm (e raised to the power of the value). Lets you enter and calculate the exponent. Completes the operation or executes the command. © 1999 TEXAS INSTRUMENTS INCORPORATED TI-30X ÙS: A Guide for Teachers A-2
