Real number functions in the MTH menu
The MTH („´) menu include a number of mathematical functions mostly applicable to real numbers. With the default setting of CHOOSE boxes for system flag 117 (see Chapter 2), the MTH menu shows the following functions:
The functions are grouped by th type of argument (1. vectors, 2. matrices,
3.lists, 7. probability, 9. complex) or by the type of function (4. hyperbolic,
5.real, 6. base, 8. fft). It also contains an entry for the mathematical constants available in the calculator, entry 10.
In general, be aware of the number and order of the arguments required for each function, 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.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 4.
Hyperbolic functions and their inverses
Selecting Option 4. HYPERBOLIC.. , in the MTH menu, and pressing @@OK@@, produces the hyperbolic function menu:
