Question about Casio FX-9750GPlus Calculator

To clear the screen press the AC/ON button (All Clear). To setup angle unit in degree rather than radian get the calculator in RUN screen. Press SHIFT MENU to enter SetUp. You see a screen similar to the following one.

Use down arrow key to bring cursor to the line Angle. Once the line is highlighted you will see three tabs at the bottom of the screen. Press the F1 key, under the TAB deg (degree). Press EXE to quit the setup screen

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

When you set some configuration parameter you must scroll down the setup until you reach the OK button. Press the OK button to validate.

Hit the DRG key to the right of the pi key. It should cycle from radians to gradians to degrees. A "D" should appear at the top of your screen rather than the current "R".

Good luck.

Paul

When the angle unit is in radians

sin^-1(0.184)=0.1850543940 radians

When angle unit is in degrees

sin^-1(0.185)=10.60283581

Your calculator is calculating the functions correctly)

In the following screen captures the sine of the values is calculated with the unit specified inside the formula (degree symbol and radian symbol are inserted to show you the unit). In the last calculation the value of the sine is practically 0.184

**Remember that when angle is in radians**, for very small angles (less than 10 degrees), **sin(x) and tan (x) are about equal to the value of the angle in radians**

sin^-1(0.184)=0.1850543940 radians

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.

Press the [MODE] key to access the mode comfiguration screen .

Set angle unit to to radian (see above)

Enter angle value in Decimal degrees only, use the [2nd][ANGLE] key sequence to have access to the degree symbol. The degree symbol must imperatively appear at the end of the angle value.

Here are some examples

If you use angle values in DMS, it will not be converted to radians, but to decimal degrees.

If you omit the degree symbol there is no conversion.

A general formula is Pi radians =180 degrees

As far as I know, the TI-81 doesn't have a degree-minute-second entry mode the later TIs have. But to answer your question, you can always do it as:

35 + 20 / 60

followed by ENTER if needed.

If you're in Radian mode instead of Degree mode, you'd have to follow up with MATH 6 to specify degrees instead of radians.

if you press the |mode| button (at the top right of the calculator) until you see Deg Rad Gra on the screen (I believe 3 presses of the mode button) and just hit the number below the rad option on the display. This will permanently change it to radian mode until you repeat this step, or clear the memory.

There is also a way to change to radian mode for just one operation if you will be mostly using degrees for example

at the bottom there is a DRG> as a shifted function. I would just recommend changing it in the way I initially outlined as there is less room for error when making calculations.

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

Press "2ND" "MODE" to enter the mode screen. Press down-arrow twice to get to the angular mode. Press right-arrow or left-arrow to highlight the desired angular mode, then press "ENTER" to select it. Exit the mode screen by pressing "2ND" "QUIT"
