One-Number Functions To use a one-number function (such as K,{ ,Q or ^) 1. Key in the number. ( You don't need to press ‘.) 2. Press the function key. (For a shifted function, press the appropriate { or | shift key first.) For example, calculate 1/32 and 148.84 . Then square the last result and change its sign. Keys: Display: Description: 32  148.84 # ! ^ Operand. Reciprocal of 32. Square root of 148.84. Square of 12.2. Negation of 148.8400. The one-number functions also include trigonometric, logarithmic, hyperbolic, and parts-of-numbers functions, all of which are discussed in chapter 4. Two-Number Functions In RPN mode, to use a two-number function (such as ›, …, z, q, , { F, | D Qor | T): 1. Key in the first number. 2. Press ‘ to separate the first number from the second. 3. Key in the second number. (Do not press ‘.) 4. Press the function key. (For a shifted function, press the appropriate shift key first.) Note In RPN mode, type in both numbers (separate them by selecting ‘ ) before selecting a function key. Getting Started 1-17
