Ti-nspire cx CAS gives answer in degrees even though it is in radians mode.

When you set some configuration parameter you must scroll down the setup until you reach the OK button. Press the OK button to validate.

My calculator is not computing sin^-1 or cos^-1 correctly, I put sin^-1(0.184) in and it came out with 10.60283... when I should be getting 1.39. HALP?

When the angle unit is in radians
sin^-1(0.184)=0.1850543940 radians
When angle unit is in degrees
Your calculator is calculating the functions correctly)
In the following screen captures the sine of the values is calculated with the unit specified inside the formula (degree symbol and radian symbol are inserted to show you the unit). In the last calculation the value of the sine is practically 0.184
Remember that when angle is in radians, for very small angles (less than 10 degrees), sin(x) and tan (x) are about equal to the value of the angle in radians

Finding radium mode on FX.........OG

You probably mean Radian mode. (the Radium is a radioactive chemical element, with symbol Ra on the Periodic table of the elements).
To set angle unit to radians, Go to the RUN screen.Press SHIFT MODE to enter SetUp. Scroll down to line ANGLE; Highlight the line and press F2 to activate the TAB RAD on the screen. Angle unit will be set to radians, until you decide to change it again.

I have to take the secant of -1.2. I'm supposed to get a degree. I can't figure out the order to push buttons. PLEASE help!

TWO THINGS YOU NEED TO KNOW, Eli.1. Secant will NEVER return a degree measure (or even a radian measure) no matter what computer or calculator you use. The reason is because secant returns the ratio of sides (hypotenuse over adjacent), which has a range of and find its reciprocal (ie, flip the number upside down: the reciprocal of 5 is one-fifth). That's all.B. TI-84 only uses the three basic trig functions. Secant is the reciprocal of cosine. Therefore, in order to find the secant of -1.2 radians you need to be in Radian mode (see #2 above). From there, you just find the cosine of -1.2 and take that values reciprocal (ie, flip the number upside down: the reciprocal of 10 is point one) . That's all. Math lesson: 1 Radian = 180 Degrees. Therefore, 1.2 Radians is roughly one-third of pi, therefore it is roughly one-third of 180 degrees; therefore -1.2 radians would be nearly -60 degrees (a very friendly angle measure). I hope that helps If not, you should call Texas Instruments because they've got friendly people who are happy to assist anyone. Questions like this are right up their ally, advanced questions like the syntax of the poisson cumulative distribution function are not. So, you're fine. For in depth math help holler at www.THEMATHCHEETAH.comIn Short: Secant returns ratios and NOT degrees or radians. Secant is the reciprocal to cosine. Arcsecant WILL return degrees/radians. Your calculator can be set to either mode.TEXAS INSTRUMENTS >>>>> all calculators ever made.

Sin, cos, and tan do not seem to work properly.

Press "Mode" Check to see if you are in radian mode or degree mode (one of the top categories)
If you are entering your numbers from sin, cos, and tan as degrees and you are in radians, your answers will be off. Same goes for if you are inputting radians while in degree mode. Hope this helps

How do I get from degrees to radians? For some reason my TI-84 will not convert degrees to radians.

Press the [MODE] key to access the mode comfiguration screen .
Set angle unit to to radian (see above)
Enter angle value in Decimal degrees only, use the [2nd][ANGLE] key sequence to have access to the degree symbol. The degree symbol must imperatively appear at the end of the angle value.


Here are some examples
If you use angle values in DMS, it will not be converted to radians, but to decimal degrees.
If you omit the degree symbol there is no conversion.


A general formula is Pi radians =180 degrees

Change Radian to Degree on HP 41CX

First of all there is three modes on HP41
You can change between them by executing the functions DEG, RAD or GRAD
To do this press XEC then ALPHA then type in the function name, then ALPHA again. A small sign will turn on on the display in case of RAD and GRAD. After this all trigonometric function will work in the selected mode.

Wrobg answer whenever I use radians

To avoid problems,set your angle unit to radians by default. Press [MODE]. If Radian is highlighted (text on black background), it is indeed the default mode. If Degreee is highlighted, scroll dowm to the line and use the left arrow to select Radian and press ENTER. Radian will start blinking.
Any number you feed a function that acts on angles (sin, cos, tan) will be considered in radians. Any result that comes out of the inverse trigonometric functions (arcsin, arccos, arctan) is in radian. The angle coming from a conversion from cartesian coordinates to polar coordinates is in radian.
You have a simple way to convert the value from radians to degrees because 1 rad=180/pi. Store this value in a variable [STO->] D
180/[2nd][PI] [STO->] D

Since the last result is always stored in [Ans] all you have to do is to multiply by D: [Ans][x][ALPHA]D converts results in degrees.

Hope it helps

Don't know how to change it from degrees to radian mode

if you press the |mode| button (at the top right of the calculator) until you see Deg Rad Gra on the screen (I believe 3 presses of the mode button) and just hit the number below the rad option on the display. This will permanently change it to radian mode until you repeat this step, or clear the memory.

There is also a way to change to radian mode for just one operation if you will be mostly using degrees for example

at the bottom there is a DRG> as a shifted function. I would just recommend changing it in the way I initially outlined as there is less room for error when making calculations.
