Angles may be measured in three angles:degree, radian and gradians (grads).

tan(45 deg)=1

tan(45 radians)=1.61977

If your problems require angles to be measured in degrees, make sure that the calculator's angle unit is set to degrees.

In RUN screen press [SHIFT][MENU] (SetUp) select the angle line and press function key under the tab Deg (should be F1).

The problem is not finding the sine of the angle but expressing the angle in Degree Minutes Seconds instead of decimal degrees.

This procedure will give you the sine regardless of the angle unit the calculator is configured for.

- In RUN screen press [SIN] function key
- Press [OPTN]
- Press [F6] to get to next page of menus.
- Press [F5:Angl]
- Enter 45 and press [F4: degree ' "]
- Enter 20 and press [F4: degree ' "]
- If you have seconds to enter, type in value and press [F4:degree ' "]
- Press [EXE] to get your result.

This procedure will give you the sine regardless of the angle unit the calculator is configured for.

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)

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)

- If angle unit is the degree just enter 15.37
- 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].

What is so surprising? The sine and cosine functions have ranges that span the closed interval [-1,1]. As to the tangent function, its range is the the whole real line.

This being said, you should keep in mind that there are three angle units: the degree, the radian, and the grad.

When you want to calculate the sine, cosine, or tangent of a number, that number is not just a number. It is an angle, and as an angle it has a unit.

For this reason a calculator generally has two angle units defined (degree and radian), and possibly the grad. BEFORE calculating any trigonometric function you must ascertain that the angle is in the correct unit.

Clearly, in the problem you are trying to solve angle values are given in degrees, but your calculator is configured to interpret angles values in radians.

To set the default angle unit to degree press [MODE] , then press down arrow twice to reach the line (radian, degree). Highlight the word degree and press [ENTER] to set the default angle unit to degree.

Unfortunately the TI 8xPLUS family of calculators does not have a status bar on screen to remind you of the modes, and if you do not remember to check the current unit you get errors (at least unexpected results).

However, there is a way to avoid the errors and that is to enter the unit explicitly after the angle value. To do that you press [2nd][APPS] to open the (ANGLE) menu list. Try it.

On this family of calculators, you do as follows

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

- 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 [ALPHA][+] (") to access the double quotation mark.
- Screen echoes 15 deg 25' 32"
- Press [ENTER]
- Calculator converts this in decimal degrees 15.42555556

Yes. Use the following procedure to enter an angle in degrees-minutes-seconds form:

Enter the number of degrees. Press "2ND" "ANGLE" "1"

Enter the number of minutes. Press "2ND" "ANGLE" "2"

Enter the number of minutes. Press "ALPHA" " (double-quote above the +)

The ANGLE key is the APPS key.

Enter the number of degrees. Press "2ND" "ANGLE" "1"

Enter the number of minutes. Press "2ND" "ANGLE" "2"

Enter the number of minutes. Press "ALPHA" " (double-quote above the +)

The ANGLE key is the APPS key.
