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.

Deg rad grad

You don't.

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.

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.

How do i set my TI-30xA calculator in radians?

Press the DRG key. Each press cycles the angle mode from degrees to radians to grads and back to degrees. The annunciator on the display will tell you what the current mode is.

How do you use the sin-1

You would press on the SIN key, "sin(" should come on the display, then enter the value, for example 3.5 or -1 so that the display shows

sin(3,5) or sin(-1) for example.

remember to close the sin with the ) on the end.
sin(-1) = -0.841470985

When I enter Sin(30)the answer is -.9880316241. This not correct. What should i do?

You have the calculator set up to do radians instead of degrees. I'm not that familiar with the TI-83 but I believe you should look for a key labeled DRG. This stands for Degrees, Radians, and, Grads. Push this key and then use the arrow keys to move from RAD to DEG and hit enter. Now enter Sin(30) and you should get 0.5.

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.

Make sure you are set to degrees, radians, or grads, whichever angular measurement you are using.

The DRG key toggles through the three modes of input, and the display shows which you are in.

30 SIN will give the correct 0.5 answer if you are set to use DEG.

Set to RAD and since 30 degrees = (30)(pi)/180= 0.52234 rad, set to RAD and 0.52234 SIN also gives you the correct 0.5 result
