SOURCE: 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.

SOURCE: HOW DO I CHANGE THE RADIANS MODE TO DEGREE MODE

Hi,

Turn calculator ON.

If you do not see icons, press MENU.

Use arrows to highlight the RUN icon and press EXE

In RUN application press SHIFT and SETUP

Use Down Arrow to highlight the line Angle

Press F1 to select Deg and press EXE.

This action will return you to the RUN application (main calculator screen).

Hope it helps.

SOURCE: casio fx-300es---how to convert radians to degrees

Hello,

You use the key combination [SHIFT][ANS] (DRG>).

**If the default angle unit is degree**

Type in the angle value in radian, say 1.2.

Press [SHIFT][ANS] (DRG>).

The screen displays 1: deg symbol, 2: a raised r for radian, and 3; a raised g (for grad).

1.2 [SHIFT][ANS] (DRG>) [2: raised r] .

The screen displays 1.2 with a raised r to the right of the 2.

Press [=].

The answer is 68.75493542

SOURCE: how the heck do you change a casio fx-9750II from radian to degre

- With calculator turned on, press [MENU] if you do not see icons.
- Use the navigation arrows to highlight [RUN-MAT] icon or press 1.
- In the Run-Mat screen press [SHIFT][MENU] to enter the (SETUP).
- Press the DownArrow 5 times to highlight the ANGLE option.
- Press [F1:Deg] to select degree.
- Press [SHIFT][EXIT] to (QUIT) the SetUp screen.
- Do your geometry ( I would say trigonometry).

When the angle unit is in radians

sin^-1(0.184)=0.1850543940 radians

When angle unit is in degrees

sin^-1(0.185)=10.60283581

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**

sin^-1(0.184)=0.1850543940 radians

The variable theta is reserved for polar plots. So if you want to graph functions of the form y= expression, you must use the default variable x. Thus draw y=sin(X). Make sure your calculator is configured with the correct angle unit (degree or radian).

If you use degrees the window dimensions for x must cover an interval of 360 degrees, to have a full period. If angle unit is radian, then choose an x-interval between [-pi and pi] or between [0 and 2pi]

Check that your angle unit is the correct one. If your problem requires degrees make sure the calculator is set to degrees also. If radians then you should set radians.
