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

Hi ssmith63,

Put the calculator in radian angle mode. The top answer is in AUTO mode and, The bottom is in Approx mode.

I converted 60 degrees into pi/3 radian which equals 1.0472 radians. I figured 5 significant digits was good enough since, you only went 4. If you have any question just post them and, I'll respond quickly.

Let su rephrase the question, just to be sure we are on the same wavelength. The cosine of an angle is 0.5: What is the value of the angle? Right?.

First of all you must set the angle unit to degree or radian.

If the angle unit is the radian, the result should be 1.045 radian.

First of all you must set the angle unit to degree or radian.

- Press [SHIFT][MODE\ and select the appropriate unit.
- Press [SHIFT][COS] to access the arc cosine function (COS^-1) enter 0.5, close the right parenthesis and hit [=]

If the angle unit is the radian, the result should be 1.045 radian.

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

Hello,

To**convert a displayed number** from degree to radian, press [2nd][DRG->] once. Each time you press the two keys in sequence you change from deg to rad to grad to degree and so on.

Hope it helps.

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

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.**

Hello,

With the TI8x/TI8xPlus you can enter an angle in degrees (Angle mode must be set to degrees) and convert it into DMS representation the following way. Exemple

18.675 [2nd][ANGLE][4] [ENTER] gives 18deg 40' 30''

If Angle [MODE] is set to degrees you can enter a number in radians and convert it into degrees. Exemple How many degrees are ther in 1rad ?

[1][2nd][ANGLE][3] display 1 with a small r as superscrit. Pressing [ENTER] yields 57.29577951

To convert 1rad into DMS, takes a little effort but can be done: you have

to convert radians to degrees and the result [ANS] into DMS.

You cannot use an angle written in DMS in any calculation.

But if you want to convert an angle from degrees to radians enter your number and divide by 57.29577951

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
