Where is the degree symbol on ti-85 - Texas Instruments TI-85 Calculator

Press SIN 4 3 2ND [ANGLE] 1 3 0 2ND [ANGLE] 2 ENTER

2ND [ANGLE] 1 gives you the degrees symbol, 2ND [ANGLE] 2 gives you the minutes symbol. If you need seconds, use ALPHA ["] (on the + key).

Note that this usually won't give you an EXACT value, but only a ten-digit approximation.

No need for such a program. You can specify the angle unit for a calculation regradless of the angle unit currently set as default.
For the TI Nspire with Touchpad.
Calculate the sine of 30 degrees.
Press the trig> button next to = on the left side of keyboard.
Select sin and press ENTER
Type in 30
Press the key with the question/Exclamation marks.
Use right arrow to highlight the degree symbol.
Press ENTER. No need to close parenthesis.
The answer is displayed as 0.5.

To enter an angle in radian (regardless of the angle unit set as default.
Do as above to type in the function
Type in the angle.
Press the small button marked with Pi and arrow (To the left under the EE button)
Use the arrow to highlight the small superscript r.
Press ENTER


For TI Nspire with ClickPad
Press the trigonometric function key.
Enter the angle
Press the key with infinity symbol, beta, degree (below the Clear button.
At the top of the list where the Pi symbol is you will find the degree,radian, and gradian symbols.
Append the one you want and and press ENTER.

You can add angle measures by hitting 2nd angle and choosing the degree option. Put this after a value (e.g. 90(degrees symbol)) and add you can add angles that way. Be sure that you are in degree mode when doing this (you can use the radian symbol for adding radians too). Still, this is a very tedious process and I recommend just adding angles as regular values (e.g. 90 + 200 = 290) and correcting for degrees manually.

To convert a value in DMS form to decimal, use the degree command in the MATH ANGLE MENU.

2ND [MATH] F3 to bring up the menu. The degree command is F1. F4 converts back to DMS.

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

The DMS symbols are available under the ANGLE menu
Press [2nd][APPS] (ANGLE)
Under that menu you find the degree and minute symbol. To enter the seconds unit you use the key sequence [ALPHA][+] (")
To enter 1deg 15 minutes and 37 seconds
1 [2nd][APPS] [1:deg] 15[2nd][Apps][2:'] 37 [ALPHA] [+]

To enter a number in decimal degrees (eg 15.37)

1. If angle unit is the degree just enter 15.37
   
2. If angle unit is the radian , you must specify the angle unit as degrees: To enter 15.37 degrees you type 15.37 [2nd][Apps][1: degree] [ENTER].

To convert from DMS to DD and from DD to DMS, you use the sequence [2nd][Apps][4:|=>DMS].

Enter the angle in degrees-minutes-seconds using the single-tick (') for all three parts. Do NOT use the degree and second symbols. In my TI-86 manual, it's on page 285.

On this family of calculators, you do as follows
Enter the first number (degrees), ex:15
Press [2nd][APPS] (ANGLE) to access the Angle functions
Select [1: degree symbol] [ENTER]
Main screen shows 15 deg
Enter the minutes, ex 25
Press [2nd] [APPS](ANGLE) to access Angle functions
Select [2:' apostrophe] [ENTER]
Screen echoes 15 deg 25'
Enter the seconds number, ex 32
Press [2nd][+] (") to access the double quotation mark
Screen echoes 15 deg 25' 32"
Press [ENTER]
Calculator converts this in decimal degrees 15.42555556

To convert this back to DMS, press [ANGLE][|=>DMS][ENTER] and the calculator displays the original value 15 deg 25' 32"

Like the TI-85, it would be in the MATH menu.
