Graphing calculator.

As they are a great number of mathematic functions available in the calculator,
the MTH menu is sorted by the type of object the functions apply on. For
example, options 1. VECTOR.., 2. MATRIX., and 3. LIST.. apply to those data
types (i.e., vectors, matrices, and lists) and will discussed in more detail in
subsequent chapters. Options 4. HYPERBOLIC.. and 5. REAL.. apply to real
numbers and will be discussed in detailed herein. Option 6. BASE.. is used
for conversion of numbers in different bases, and is also to be discussed in a
separate chapter. Option 7. PROBABILITY.. is used for probability
applications and will be discussed in an upcoming chapter. Option 8. FFT..
(Fast Fourier Transform) is an application of signal processing and will be
discussed in a different chapter. Option 9. COMPLEX.. contains functions
appropriate for complex numbers, which will be discussed in the next chapter.
This option will be presented later in this section. Finally, option 11. SPECIAL
FUNCTIONS.. includes functions of advanced mathematics that will be
discussed in this section also.
In general, to apply any of these functions you need to be aware of the
number and order of the arguments required, and keep in mind that, in ALG
mode you should select first the function and then enter the argument, while in
RPN mode, you should enter the argument in the stack first, and then select
the function.
1. Since the operation of MTH functions (and of many other calculator
menus) is very similar, we will describe in detail the use of the 4.
HYPERBOLIC.. menu in this section, with the intention of describing the
general operation of calculator menus. Pay close attention to the process
for selecting different options.
2. To quickly select one of the numbered options in a menu list (or CHOOSE
box), simply press the number for the option in the keyboard. For
