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.

85-84cos(25 deg)=8.87015 and I do not see how you get 3. If angle is in radians the answer is 1.73896. Make sure your calculator is configured to use the right angle unit (radian, degree or gradian).

The sine of 0.5 radians is about 0.4794, so your calculator seems to be giving you the correct answer in that case.

The sine of 0.5 degrees is about 0.00872, which your calculator may be displaying as something line 8.72 times ten to the negative 3. Look to the far right end of the number: do you see "x10-3" with the "-3" superscripted? In that case, again your calculator is giving you the correct answer.

When you are handling trigonometric functions and their inverses, the results depend on the angle unit your calculator is configured for.

When angle is in degrees, tan (1/2)=8.726867791x10^(-3)

When angle is in radians, tan(0.5 radians)=0.5463024898

It seems that your angle unit on calculator is set to degrees, while it should be set to radians.

Hello,

Press [MODE] and select [1:COMP]

Press [SHIFT][MODE] and select [3:Deg]. You can also use rad if the angle you are given is in radians.

To start the conversion

Press [SHIFT][-] (Rec) screen displays**Rec(**

Key in the radius r , ex: 3 screen displays**Rec(3**

Press [SHIFT][)] (,) to enter comma separator **Rec(3,**

Key in the angle in degrees, ex: 57.3; screen displays **Rec(3,57.3**

Press ) to close parentheses; screen displays **Rec(3, 57.3)**

Press [=]

Screen displays

**Rec(3, 57.3)**

**X=1.620720961**

Y=2.524532346

X and Y are the values of the coordinates. ** **

If angle is in radians, [SHIFT] [MODE][4:Rad] the command

Rec(3, Pi) gives X=-3, Y=0

I just realized that your question pertains to the FX82MS but is listed under the FX115ES (That is quite a difference) So my answer above does not concern you but I will leave it as is should anyone need the answer for the FX115ES.

Look at the enclosed screen capture for the FX82MS

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

Hello,

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

Alot of people seem to be having this problem. Angles can be measured in two units, degrees and radians. Your calculator is currently doing everything in terms of radians. I have an 84 but I'm sure the 83 is similar, go under MODE and look for Degrees and Radians and make sure you choose degrees. if you have to convert 360[degrees] = 2* pi [radians]

(easy to remember, 360deg in a circle, 2pi radians in a circle)

Good luck
