I cannot figure out how to square or cube the cosh function or the others i.e. csc, sin, cos, etc. Is there a way to do this.......

1) Selecting the sin/cos/tan key results in sin( or cos( or tan( being displayed on your computer, 2) press [in succession] x,).

Your calculator should now be displaying cos(x). Recall that the typed cos^2(x) means that the result of cos(x) is squared. Simpler: typed cos^2(x) = (cos(x))^2.

Continuing from above: 3) press the left arrow [<-] until the cursor is on the left side of cos(x), 4) add another "(", 5) now press the right arrow until the cursor is on the far right side of what is now (cos(x), 6) add a ")" here (you should now have (cos(x)), 7) now press the ^ and 2 (you should now have (cos(x))^2), and

7) PRESS Enter and Whalaaaa

What are you guys talking about ? i tried this.. it doesnt work..

How do you type sin squared x in TI-89 ?

i mean sin^2(x) .

Say you want to square sin(3).. Press: sin 3 ) And then press the button on the left that has the X Squared on it.

csc(x)=1/sin(x)

sec(x)=1/cos(x)

csc(x)/sec(x)=(1/sin(x))*(cos(x)=cot(x)

csc(x)*cot(x)/sec(x)=(cot(x))^2=(tan(x))^(-2)

sec(x)=1/cos(x)

csc(x)/sec(x)=(1/sin(x))*(cos(x)=cot(x)

csc(x)*cot(x)/sec(x)=(cot(x))^2=(tan(x))^(-2)

Circumference of a Circle: 2 x pi x radius - OR - pi x diameter,

or if you need some sphere calculations?

Sphere Surface Area: 4 X pi X radius squared OR

pi X diameter squared Sphere Volume: 4/3 X pi X radius cubed OR

( pi X diameter cubed ) / 6

By the way.......... "pi" = 3.1415926536

The hyperbolic cosine is defined as (e^x+e^(-x))/2. This makes the cosh of -x as (e^(-x)+e^x)/2, which is the same thing except for the order of the two terms in the sum. Thus cosh(x) is equal to cosh(-x), and thus cosh is an even function.

Sorry I do not like to work with secant and cosecant.

sec(a)+tan(a)=(1+sin(a))/cos(a)

ln(sec(a)+tan(a))=** ln( (1+sin(a))/cos(a))=X**

2*cosh(X)= e^(X)+e^(-X)

**e^(X)=(1+sin(a))/cos(a)**

**e^(-X)= cos(a)/(1+sin(a))**

2cosh(X)=(1+sin(a))/cos(a) +cos(a)/(1+sin(a))= 2/cos(a)

**cosh(X)=1/cos(a)=sec(a)**

Now that you see how you can do it, I trust you will discover any mistake I might have made.

If you want to use the classPad function sequence**Action>Transformation>simplify(,** do it step by step as I have detailed above.

Good Luck.

The INV key that you may find on some scientific calculators has, on the TI 83/84/ Plus calculators, an equivalent key marked [2nd].

On the TI83/84 Plus, each trigonometric function has a second marking [SIN^-1], [COS^-1] or [TAN^-1]. To calculate the inverses of trigonometric functions ( arc sine, arc cosine, arc tangent) you press [2nd] followed by the relevant trigonometric function key For example, [2nd] [SIN] displays sin^-1( on the command line.

Unfortunately the hyperbolic functions and their inverses are only accessed through the CATALOG. You press [2nd][0] to open the CATALOG. Then you scroll down the CATALOG list to reach cosh(, cosh^-(, sinh(, sinh^-1(, tanh(, or tanh^-1(.

To speed the search in the catalog, you use the ALPHA keyboard: To reach cosh(, press[PRGM] and you scroll down from there.

The FX-115ES is somewhat different to other calculators you might know. The sequence of keys is more like writing up a calculation in a textbook, whereas for "normal" calculators operations are reversed in some places.

For example, with most calculators you would type 30 [sin] to calculate the sine function of 30 degrees, with the 115ES its [sin] 30 [=].

The 115ES has all the standard trigonometric functions:

The 115ES has all the standard trigonometric functions:

- Standard functions (sin, cos, tan), type the [sin], [cos] or [tan] key followed by the argument.
- Inverse trigonometric (sin?¹, cos?¹, tan?¹), type [SHIFT][sin], [SHIFT][cos] or [SHIFT][tan] followed by the argument.
- Hyperbolic functions (sinh, cosh, tanh), type [HYP][sin], [HYP][cos], or [HYP][tan] followed by the argument.
- and finally inverse hyperbolic (sinh?¹, cosh?¹, tanh?¹), its [SHIFT][HYP][sin], [SHIFT][HYP][cos], or [SHIFT][HYP][tan] followed by the argument.

x^ is marked on the keyboard as an x with a superscript rectangle on the key above the sin key. This function lets you raise a value to any number, including 2 and 3.

Press the relevant function key [SIN],[COS],[TAN] followed by the angle value.

For inverse trigonometric functions [SIN^-1], COS^-1], or [TAN^-1], Press [SHIFT][SIN], [SHIFT][COS], or [SHIFT][TAN].

For other functions

sec(x)=1/cos(x)

csc(x)=1/sin(x)

cot(x)=1/tan(x)

When calculating trigonometric functions one must make sure that the angle unit the calculator is using is the correct one.

Hello,

I have not yet seen a calculator that has a dedicated key for the cosecant , secant, nor cotangente functions, because they are directly connected with the sine, the cosine, and the tangente.

Cosecant (x) = 1/sin(x)

Secant (x) = 1/cos(x)

Cotangente(x) = 1/tan(x)

Do not confuse these functions with the inverse trigonometric functions, usually represented as

arccosine = arccos; on calculators cos^-1,

arcsine = arcsin ; on calculators sin^-1

arctangent= arctan ; on aclculators tan^-1

Hope it helps.
