How To Put Calculator In Radian Mode

The functions housed in the Angle menu on your TI-84 Plus reckoner enable you to convert betwixt degrees and radians or convert between rectangular and polar coordinates. To convert degrees to radians, follow these steps:

1. Put the calculator in Radian mode.

   Press [MODE], apply the pointer keys to highlight RADIAN, and then press [ENTER].

2. If necessary, press [2nd][Style] to access the Abode screen.

3. Enter the number of degrees.

4. Press [2nd][APPS][1] to paste in the caste function.

5. Printing [ENTER] to convert the caste measure to radians.

   This is illustrated in the first screen.

   If you're a purist who likes to see radian measures expressed as a partial multiple of pi whenever possible, standing with the following steps accomplishes this goal if it's mathematically possible.

6. To divide the radian measure by pi, press

   

   This is illustrated in the 2d screen.

7. Printing [MATH][ENTER][ENTER] to convert the result to a fraction, if possible.

   This is illustrated in the third screen. If the figurer can't catechumen the decimal obtained in Step vi to a fraction, it says so by returning the decimal in Footstep 7.

   

To catechumen radians to degrees:

1. Put the computer in Degree mode.

   Press [Way], utilize the pointer keys to highlight DEGREE, and so printing [ENTER].

2. If necessary, press [2nd][MODE] to admission the Home screen.

3. Enter the radian measure.

   If the radian measure is entered as an arithmetic expression, surround that expression with parentheses.

4. Press [2nd][APPS][iii] to paste in the r function.

5. Press [ENTER] to catechumen the radian measure to degrees.

   This is illustrated in the first screen.
