combination „´ . With the default setting of CHOOSE boxes for system
flag 117 (see Chapter 2), the MTH menu is shown as the following menu list:
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. Option 10.
CONSTANTS provides access to the constants in the calculator. 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.
Using calculator menus:
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
example, to select option 4. HYPERBOLIC.. in the MTH menu, simply press
