How is Tanh calculated?

How is Tanh calculated?

tanh ( x ) = sinh ( x ) cosh ( x ) = e 2 x − 1 e 2 x + 1 . tanh ( x ) = − i tan ( i x ) .

How do you program a TI 89 calculator?

How to enter a new program

1. While on the Home screen, hit APPS. Open the PROGRAM EDITOR menu.
2. Type in the name of the program in the box labeled VARIABLE. Choose a descriptive name up to 7 letters.
3. Now you are ready to type in each line of your program. You will notice that some lines have already appeared.

How do you calculate Coshx?

cosh x = ex + e−x 2 . The function satisfies the conditions cosh 0 = 1 and coshx = cosh(−x). The graph of cosh x is always above the graphs of ex/2 and e−x/2.

How is hyperbolic sine calculated?

Hyperbolic Trigonometric Identities. The hyperbolic sine and cosine are given by the following: cosh ⁡ a = e a + e − a 2 , sinh ⁡ a = e a − e − a 2 .

What is Coshx and Sinhx?

Definition 4.11.1 The hyperbolic cosine is the function coshx=ex+e−x2, and the hyperbolic sine is the function sinhx=ex−e−x2.

What programming language does TI-89 use?

TI-BASIC 89
The TI-89 is directly programmable in a language called TI-BASIC 89, TI’s derivative of BASIC for calculators. With the use of a PC, it is also possible to develop more complex programs in Motorola 68000 assembly language or C, translate them to machine language, and copy them to the calculator.

How to do complex numbers on a TI 89?

Once only, you need to tell the TI-89 that you want results in rectangular mode. [MODE] [▼ 5 times] [►] brings up the choices for complex format. Select [2] for Rectangular and press [ENTER]. For complex numbers in rectangular form, the other mode settings don’t much matter. Polar Display Mode

Where can I find hyperbolic functions in the catalog?

The hyperbolic functions are available only from the CATALOG. The table below lists the hyperbolic functions in the order in which they appear among the other CATALOG menu items. The ellipses in the table indicate the presence of additional CATALOG items.

Can a complex variable be defined as a hyperbolic function?

This online calculator computes the following hyperbolic functions of a complex variable , where and are real numbers. Since the exponential function can be defined for any complex argument, we can also extend the definitions of the hyperbolic functions to complex arguments. The hyperbolic sine function of a real variable is defined by:

What does rectangular mode mean on the TI-89?

Rectangular mode means you want answersin a+bi form, whether you use polar or rectangular form when entering your expressions. Once only, you need to tell the TI-89 that you want results in rectangular mode. [MODE] [▼ 5 times] [►] brings up the choices for complex format.
