Negation of 148.84.
The one-number functions also include the trigonometric functions,
the logarithmic functions, the hyperbolic functions, and the parts-of-
numbers functions, all of which are discussed in chapter 4.
Two-Number
Functions
To use a two-number function (such as (T)/
Q/
E/
and
f+"lV»
1. Key in
the
first number.
2. Press I
enter
Ito separate the first number from the second.
3. Key in the second number. (Do not
press
I
enter
I.)
4. Press the function key. (Fora shifted function, press the shift key
first.)
Remember
to
enter
both
numbers
before
executing
the
function.

The order of entry is, of course, essential for noncommutative func
tions such as Q
and
(+]• If
the
numbers have
been
entered in the
wrong order, you can still get the correct answer without re-entering
the numbers by pressing |x$y| to swap the
order
of the
numbers.
Then
perform the
intended
function. (This is explained in detail in chapter
2
under
"Stack Manipulations.")
