How can I use secant and cosecant functions on the TI 30XA? I am currently needing these functions for navigating great circle calculations.

If the sides of a triangle are 15cm ,16cm, and 17 cm ,then the area of the triangle is what ?

Cosecantx = 1/sinx

secantx=1/cosx

cotangent=1/tanx

Use these identities to get at the trig functions not represented on the calculator.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Also to get the angles you need to use the inverse trig functions (for example sin^(-1) (2nd SIN))

Hi,

A 6ya expert can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

Good luck!

It means your calculator is set to degrees mode. Angles can be measured using three different units: degrees (360 degrees in a circle), radians (2pi radians in a circle), or grads (400 grads in a circle).

Pressing the DRG key cycles through the three modes. No matter which mode you select, one of the annunciators will appear on the screen to indicate the current mode.

There are no keys for cosecant, secant, and cotangent. You can calculate those ratios as

csc(x) = 1/sin(x)

sec(x) = 1/cos(x)

cot(x) = 1/tan(x)

Simply calculate the trig ratio on the right and then take its reciprocal.

csc(x) = 1/sin(x)

sec(x) = 1/cos(x)

cot(x) = 1/tan(x)

Simply calculate the trig ratio on the right and then take its reciprocal.

Use x-1 to calculate 1/x (x to the negative-one power).

What I think you're calling the inverse function keys actually calculate arcsine, arccosine, and arctangent.

To calculate cosecant x, for example, use the relationship

csc(x) = 1/sin(x)

"Input" is a command, which inputs a value. Try this:

Input X:tan^-1(1/X)

Input X:tan^-1(1/X)

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,

The cosecant function is defined by

**cosec(x) = 1/sin(x) **

1[/] [sin] x.

Do not confuse this function with the arcsine function which is accessed by [2nd][sin to the -1]. When you use trigonometric functions make sure that the angle unit (Rad, dgree, grad) is the one you want.

Hope it helps.

try inputting using brackets (sin(angle))^-1 or 1/(sin(angle))

because cotangent, cosecant, and secant are all inverse trig functions, just type in 1 / |shift| trig function and the number if you are finding the angles. It might not be a dedicated button, but its an extra push, and it will give you the same result. *note that I put the shift press only because that is how you get the inverse tan to get an angle from a tan ratio.*

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.
