Chapter 2: Math, Angle, and Test Operations 60
Entry Notation
DMS (degrees/minutes/seconds) entry notation comprises the degree symbol (¡), the minute
symbol (
'), and the second symbol ("). degrees must be a real number; minutes and seconds must be
real numbers ‚ 0.
Note: DMS entry notation does not support fractions in minutes or seconds.
degrees¡minutes'seconds"
For example, we know that 30 degrees is the same as p/6 radians, and we can verify that by
looking at the values in degree and radian modes. If the angle mode is not set to Degree, you must
use ¡ so that the TI-84 Plus can interpret the argument as degrees, minutes, and seconds.
Degree
¡ (degree) designates an angle or list of angles as degrees, regardless of the current angle mode
setting. In Radian mode, you can use ¡ to convert degrees to radians.
value¡
{value1,value2,value3,value4,...,value n}¡
¡ also designates
degrees (D) in DMS format.
' (minutes) designates minutes (M) in DMS format.
" (seconds) designates seconds (S) in DMS format.
Note: " is not on the ANGLE menu. To enter ", press ƒ [ã].
