After you have enter the inverse of sin into the calculator, how do you get the degree of that angle?


Make sure the calculator is set to degrees. Press MODE and ensure that "DEGREE" is highlighted on the third line. Press 2ND QUIT to get out of the mode screen.

To calculate the inverse sine of 42/57, press
2ND SIN^-1 4 2 / 5 7 ENTER

The arcsine of 42/57 is about 47.46 degrees.

How do i go from dms to decimal degrees with my ti-30x IIs


Press the key that is marked with a small circle, an apostrophe, and a double quotation mark. That is the DMS key. You can use it to convert from Decimal degress to DMS and back.

When I hit dms function the answer comes out wrong the degree minutes = the degree and the seconds = the minutes how do I change it TI-84 Silver


At first, you have to use DEGREE mode and after that you can convert your angles into DMS mode. See captured image below

I know how to convert between decimal degress and degrees, minutes, seconds, but how do you enter degrees, minutes, and seconds directly?


Enter it as DD.MMSS and then press 2nd [DMS-DD] to convert it to decimal for further calculations.

For example, to enter 21 degrees 34 minutes 45 seconds, enter 21.3445 then press 2nd [DMS-DD].

How do I get from degrees to radians? For some reason my TI-84 will not convert degrees to radians.

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

How do you put degrees mins & secs in a ti 84 plus


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].

How do I find degrees minutes and seconds on my ti 84 plus?


On this family of calculators, you do as follows
  1. Enter the first number (degrees), ex:15
  2. Press [2nd][APPS] (ANGLE) to access the Angle functions
  3. Select [1: degree symbol] [ENTER]
  4. Main screen shows 15 deg
  5. Enter the minutes, ex 25
  6. Press [2nd] [APPS](ANGLE) to access Angle functions
  7. Select [2:' apostrophe] [ENTER]
  8. Screen echoes 15 deg 25'
  9. Enter the seconds number, ex 32
  10. Press [ALPHA][+] (") to access the double quotation mark.
  11. Screen echoes 15 deg 25' 32"
  12. Press [ENTER]
  13. 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"

Converting degrees and minutes and seconds to radians


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

Hope it helps
