Question about Measuring Tools & Sensors

The 3 trig functions most commonly

used in triangle calculations are

sine = Opposite/Hypotenuse Co secant = Hypotenuse/Opposite

Cosine = Adjacent/Hypotenuse The reciprocals are Secant = Hypotenuse/Adjacent

Tangent = Opposite/ Adjacent Cotangent = Adjacent/Opposite

Hope this helps Loringh

Possible: Inverse trigonometric functions have limited domains. For arcsine and arccosine it is between -1 and 1.

To get the inverse trigonometric functions press the 2nd key then the trig function key. If you'll look at the key legends above the SIN, COS, and TAN keys you'll see the standard math notations for their inverse function.

For the reciprocal of a number, enter the number then press the key marked with an x^-1. You might have to use the SHIFT key first. For inverse of trigonometric functions use the SHIFT key followed by the function name. The inverse of LN is e^x. The inverse of log is 10^x. To calculate the inverse of a matrix, enter the name of the (already created) square matrix then press x^-1.

To get results in radians you must configure the angle unit to be degree.

- In Run screen press [SHIFT][MENU] to access (SETUP).
- Use Down arrow to highlight the line Angle :
- Press F2 key to select the TAB Radian.
- Once you do that all values (input of trigonometric functions and polar graph functions OR output of inverse trigonometric functions) are in radians.

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.

The inverse trigonometric function share each the same physical key with its direct function. The inverse trigonometric functions are accessed with the [SHIFT] key

[SHIFT] [SIN] accesses the arcsine

[SHIFT][COS] accesses the arccosine

and [SHIFT][TAN] the arctangent.

[SHIFT] [SIN] accesses the arcsine

[SHIFT][COS] accesses the arccosine

and [SHIFT][TAN] the arctangent.

By definition

On this calculator, you have two ways to calculate one of these functions. EX cosecant of 37 degrees

- cosecant of X =1/sin(X), must not be confused with arc sine [sin^-1]
- secant of X =1/cos(X), must not be confused with arc cosine [cos^-1]
- cotangent of X =1/tan(X), must not be confused with arc tangent [tan^-1]

On this calculator, you have two ways to calculate one of these functions. EX cosecant of 37 degrees

- You enter 1 / [sin] 37 [ ) ] [ENTER] result is 1.661640141
- You enter [sin] [ ) ] 37 [ENTER] followed by [X^-1] to take the reciprocal of the previous answer. The [X^-1] key is the one just below [MATH].

Hello,

That habit of TI, Casio, and Sharp to label the inverse trigonometric functions with the -1 superscript can cause confusions.

Hope it helps

That habit of TI, Casio, and Sharp to label the inverse trigonometric functions with the -1 superscript can cause confusions.

- The inverse trigonometric functions arcosine, arcsine, and arctangent (labeled by manufacturers as cos^-1, sin^-1, and tan^-1) should not be confused with the other trigonometric functions known as secant(x) =1/cos(x), cosecant(x)=1/sin(x) and cotangent(x) = 1/tan(x).
- To avoid errors in the use of the inverse trigonometric functions, one must be careful and set the angle unit to the one required by the problem at hand (degrees, or radians)
- To make the trigonometric functions really functions, their range is restricted.
- In this calculator arcosine (x) gives results between 0 and 180 degrees (if angle MODE is Degree) or between 0 and Pi radians (if angle MODE is Radian).
- The range of results for arcsine(x) and arctangent(x) is between -90 degrees and +90 degrees (if angle MODE Degree) or -Pi/2 and Pi/2 (if angle MODE is Radian)

Hello,

Yes it does. All scientific calculators do logs, power, roots, exponential, trigonometric functions. Most do also hyperbolic and inverse hyperbolic functions.

Hope it helps.

Sorry but you are not been very clear.

Are you doing some kind of geometry or trying to use the inverse trigonometric functions such**as arccos, arcsin, arctan?**

If you are doing geometry you should specify what application you are using.

If it concerns the trigonometric functions, on the TI83/TI83Plus these functions are represented as cos^-1, sin^-1, tan^-1.

To access them you press the**2nd ** (orange/yellow) then **cos, sin or tan.**

A word of caution:When using any trigonometric function make sure your calculator is configured with the correct angle unit ( degree or radian)** **your problem calls for.

Good luck,

Hope it helps.
