Example
Perform the following hyperbolic calculations.
Two-Number Functions
When a function requires two numbers, other than for addition, subtraction, multiplication,
division, and the power function, ( ), you may key in the numbers as follows: number1 Æ
number 2 followed by the operation. Pressing Æ evaluates the current expression and
displays the INPUT annunciator.
In-line Functions
For calculations involving \¨, \Ä, \Ç, ]9,
]<,]I, and ]oI, which require two numbers, you may also
key in the first number followed by the function keys, and then key in the second number
followed by 4 to return results. Throughout the manual, when examples are entered in this
manner without using Æ, they are referred to as in-line functions. For example, the
following keystrokes calculate the percent change between 17 and 29 using the \¨
keys as an in-line function:
