First try this- press the 2nd key and press and hold the up arrow key or the down arrow on the right side of the calculator a for a few seconds and see if the curser appears - if it does - than problem solved . to set the calculator to degree mode press the MODE button and find Radain, degree and hightlight it by moving the curser over it and press enter than exit it now set to degree and press sin(30 and enter and see if you get .5 as a result it it does than problem solved

Make sure the calculator is set to degrees. Press MODE and ensure that "DEGREE" is highlighted on the third line. Press 2ND QUIT to get out of the mode screen.

To calculate the inverse sine of 42/57, press

2ND SIN^-1 4 2 / 5 7 ENTER

The arcsine of 42/57 is about 47.46 degrees.

It means your calculator is set to degrees mode. Angles can be measured using three different units: degrees (360 degrees in a circle), radians (2pi radians in a circle), or grads (400 grads in a circle).

Pressing the DRG key cycles through the three modes. No matter which mode you select, one of the annunciators will appear on the screen to indicate the current mode.

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.

That is the correct answer if the angle is 60 radians. If you want to work in degrees, press MODE to bring up the mode screen. Use the arrow keys to highlight "Degree", press ENTER, then 2nd QUIT to exit the mode screen. Now 12 divided by the sine of 60 degrees will give about 13.9.

Yes, there is a feature or, setting in the mode that will stop you from converting fractions. Go to the mode screen by pressing the [MODE] key. [Down arrow] 9 times and, highlight and select the n/d by pressing the [ENTER] key. Next, [Down arrow] 1 time and, highlight and select Frac by pressing [ENTER] key. Just escape or, quit out of the mode screen and, the calculator should now be set up to convert your fractions. Just remember to go back and, change the last setting you made when you go back to dealing with decimal numbers.

You must first set angle unit to degree.

Press the [MODE] key a certain number of times until you get to a screen that displays Deg Rad Grad. Press number key 1 to select degree.

Once this is done you can calculate trigonometric functions. To enter angles in DMS you have a key marked with degree symbol, a quotation mark, and a double quotation mark. In what follows that key is represented as DMS.

To calculate cos(30 deg 24')

[COS] 30 [DMS] 24[DMS] [=]

If you get an error message you will have to enter the seconds even if the value is 0

[COS] 30 [DMS] 24[DMS] 0 [DMS] [=]

If you want to use degrees (to have a DEG appear on top of the screen) you must exit all base-N modes (bin, oct, hex, or pent if available) and set the calculator numeration mode to DEC, decimal (the usual computational moode). The other modes are appropriate for handling certain types of calculations with integer (whole) numbers.

Hi,

Maybe some of your answers are wrong, but I can assure you that it has nothing to do with the poor deg indicator sitting on the top of your screen.

The indicator is there to remind you that the angle unit is set to degree, meaning any number you feed a trigonometric function is considered to be in degrees, and that any value calculated by an inverse trigonometric function is in degrees.

If you prefer to work in radians or in grads, all you have to do is change the settings of the calculator.

To change angle unit:

Press [SHIFT][MODE] and choose

I suggest you look at the manual that shipped with your calculator. Lookk for exemples of the calculation you want. Make a note of the exemple numbers and check the appendix for the particular exemple. The appendix will show you all the key strokes.

Hope it helps.

Thank you for using FixYa.

The [MODE] key can be used to select the modes described below.

Important! The following is a general explanation of Scientific Calculator modes. Note that your calculator may not include all of the modes described here.

1) Calculation Modes

Before performing a calculation, you first need to select the appropriate calculation mode.

COMP: Basic arithmetric calculations

(arithmetic operations, trigonometric functions, etc.)

COMPLEX: Complex number calculations

SD: Single-variable statistical calculations

(sample standard deviation, etc.)

LR or REG: Paired-variable statistical calculations

(linear regression statistical calculations, etc.)

BASE or BASE-n: Binary, octal, decimal, hexadecimal number system calculations

MAT: Matrix calculations (determinants, etc.)

VCT: Vector calculations

EQU: nth degree equations, simultaneous equations

2) Display Settings

Use these settings to control how calculation results are displayed.

Note that changing the Fix and Sci settings does not affect internal calculation results.

Norm: Exponential display format and cancels the currently configured Fix and Sci settings.

Fix: Specifies a fixed number of digits to the right of the decimal place.

Sci: Specifies a fixed number of significant digits.

3) Angle Unit Setting

(90°=?/2 radians=100 grads)

Deg: Degrees

Rad: Radians

Gra: Grads

4) Engineering Mode

Use this mode when you want to input and perform calculations using engineering symbols.

Under the screen you can see atable of values at the right of which is written MODE followed by a small arrow.

If you want to set the degree as angle unit, you press the MODE key followed by 4 (as seen in the table I was referring to).

Similarly, if you want to set RAD as the angle unit you press MODE then 5; and MODE then 6 for GRAD.

However if you just want to convert a number displayed on the screen in RADs or GRADs into DEGs , you press SHIFT then MODE then 4. your number should be converted from the unit it was expressed in into degrees.

Same thing if you want to convert into RADs: SHIFT then MODE then 5.

Hope it helps.
