Question about Texas Instruments TI-83 Plus Calculator

You have the calculator set up to do radians instead of degrees. I'm not that familiar with the TI-83 but I believe you should look for a key labeled DRG. This stands for Degrees, Radians, and, Grads. Push this key and then use the arrow keys to move from RAD to DEG and hit enter. Now enter Sin(30) and you should get 0.5.

Set the angle unit to degrees.

Try sin (30)=, and 30 sin

**The correct answer is 0.5**

Usually if pressing the sin key display**sin(** then you should use **sin(angle) =**.

Try sin (30)=, and 30 sin

Usually if pressing the sin key display

The sine of 30 radians is about -0.988 while the sine of 30 degrees is 0.5 .

To change the angular setting, press MODE, down-arrow to the "Radian Degree" line, highlight Degree, press ENTER, then 2nd QUIT to exit the mode screen.

Make sure you have the proper angular mode set. The TI-84 can work with degrees or radians.

Press MODE to bring up the mode screen. Use the arrow keys to highlight either "Radian" or "Degree" on the third line and press ENTER. Press 2ND [QUIT] to exit the mode screen.

If this doesn't do it, please reply to this post giving an example of a calculation and the answer you're getting from the calculator.

- Press MODE 9 to shift into Normal display mode, or MODE 7 and enter the number of digits you want to see.
- sin 30 EXE. Be aware that the result depends on the angular mode. Most math problems are specified in radians, while your example sounds like it's in degrees. To select degrees, press MODE 4. To select radians, press MODE 5.
- 30 * sin 30 EXE. Everything in #2 above applies.

You would press on the SIN key, "sin(" should come on the display, then enter the value, for example 3.5 or -1 so that the display shows

sin(3,5) or sin(-1) for example.

remember to close the sin with the ) on the end.

**sin(-1) = -0.841470985**

sin(3,5) or sin(-1) for example.

remember to close the sin with the ) on the end.

The problem is that you have the mode in radians. You want them in degrees. This is a simple fix. Press mode and then go down to radians and select degrees

Make sure you are set to degrees, radians, or grads, whichever angular measurement you are using.

The DRG key toggles through the three modes of input, and the display shows which you are in.

30 SIN will give the correct 0.5 answer if you are set to use DEG.

Set to RAD and since 30 degrees = (30)(pi)/180= 0.52234 rad, set to RAD and 0.52234 SIN also gives you the correct 0.5 result

The answer that you have received in actuality is correct. However, it
is in exact form when the answer that you were looking for was an
approximation (decimal form) answer. To achieve this all you have to
do is hit the alpha button (the yellow button with a diamond in the
center) and then enter which will give you your desired answer :-)

here are the steps in changing it from radian to degrees

1. turn on your TI-83 plus

2. press the MODE button near the top of your calculator

3.go down to options and move the highlight from radian to degree, press enter and clear

you're good to go
