User manual TEXAS INSTRUMENTS TI-40 COLLEGE II QUICK REFERENCE

[. . . ] APDTM (Automatic Power DownTM) turns off the TIN40 Collge automatically if no key is pressed for about 5 minutes. 2-Line Display: The first line (Entry Line) displays an entry of up to 88 digits (or 47 digits for Stat or Constant Entry Line). Entries begin on the left; those with more than 11 digits scroll to the right. or % " to move the cursor immediately to the beginning or end of the entry. [. . . ] If you want to choose the factor (instead of letting calculator choose it), press }, enter the factor (an integer), and then press <. displays DIV on the entry line and the divisor used to simplify the last fraction result. % O converts between a mixed number and a simple fraction. % 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. Stored Operations m o % n p The TIN40 Collge stores 2 operations, OP1 and OP2. Enter the operation (any combination of numbers, operators, or menu items and their arguments). The TIN40 Collge automatically calculates the result (without pressing <) and displays the counter (as space permits) on the left side of the result line. When you press m or o more than once in succession, the counter increments by 1. You can set the TIN40 Collge to display the counter and the result only (excluding the entry). Repeat to toggle this setting off. Memory z L %h{ Pi g The TIN40 Collge has 5 memory variables--A, B, C, D, and E. You can store a real number or an expression that results in a real number to a memory variable. % { clears all variable values. p=3. 141592653590 for calculations. In RAD mode, p is represented as Pi in results of multiplication or fraction calculations. The TIN40 Collge only accepts p in the numerator of a fraction. Notation %, C Angle Modes %I = % I displays a menu to change the Angle mode to degrees or radians. = displays a menu to specify the Angle unit modifier-- degrees (), radians ( r), or DMS ( ). 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 Select a unit modifier ( r ) for any part of an entry. Entries with unit modifiers are interpreted accordingly, overriding the Angle mode. To convert an entry: Set the Angle mode to the unit you want to convert to. (Angles of trig functions convert values inside parentheses first. ), or -2- % , displays the Decimal Notation mode menu. Press M before entering a negative exponent. Stats %twvu 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. Press $. In 1-VAR stat mode, enter the frequency of occurrence (FRQ) of the data point.
