ANGLE 3: r Radian notation 4: 8DMS Displays as degree/minute/second 5: R8Pr( Returns r, given X and Y 6: R8Pq( Returns q, given X and Y 7: P8Rx( Returns x, given R and q 8: P8Ry( Returns y, given R and q 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 mode Radian mode 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].
