Change the angular mode to something other than radians.

Radians in texas calculator


Press [2nd][.] (FORMAT). Press the DownArrow (INS). You will se the angle unit displayed as DEG. Press [2nd][ENTER] to set angle unit to RAD. You will see RAD displayed. Press [2nd][CP] to (QUIT).
Keep in mind that this is a financial calculator and that the number of decimal digits is by default set to 2.
If you use it to calculate values of some scientific functions you must keep more digits. To change the number of digits in display, press as before [2nd][.] (FORMAT]. The display will show DEC= and the current number of decimal digits. Key in a value between (0, and 9) and press ENTER. Press [2nd][CPT] to (Quit).

I want to remove rad and sci symbol from casio fx-901 calculator display


For removing SCI symbol press following keys Shift-->Mode-->8-->1.
You can't remove RAD symbol, you can only replace it by DEG or GRA.

I dont know how to do a Trig problem on my classpad 330


Press the keyboard button to display the soft keyboard on screen. By default it will show the tabs mth abc cat 2D

Tap the TRIG tab at the bottom of soft keyboard. The trigonometric functions will become available to you.

To make sure you are using the correct angle units look at the bottom of screen where it says Alg Standard Real Rad. If you use degrees instead of Rad it should display Deg.

To set the correct angle unit, press the Setting icon at the lowest left of screen and choose radian or degree and select decimal calculation if you need evaluated decimal results. Tap the set button to validate your choices.

DEG mode


The DEG indicator has absolutely nothing to do with division, fraction or other operations. It is relevant only when you are calculating trigonometric functions (Sine, Cosine Tangent and their inverse functions.)

When you are calculating trigonometric functions the results depend on the angle unit the calculator is configured for
DEG >> angle values are in degrees.
RAD>> angle value are in radians

From the equivalence 180 deg =Pi radians you get
1 rad= 180deg/Pi=180 deg/3.14..=57.29577951 degrees.

The DEG indicator merely reminds you that angles are in DEG. If you change the unit to RADians the RAD indicator will be displayed instread.

FIX/Mode problem?


I do not think that the DEG and FIX indicators are preventing you from calculating any logarithm. DEG appears to remind you that the CURRENT angle unit is the degree. You can change it to RAD or GRAD if you have to use those units. However, DEG will disappear only if replaced with RAD or GRAD.

The indicator FIX reminds you that the display mode for the results is the FIXed mode, not the SCIentific mode. In the FIX mode you specify the number of decimal digits from 0 to 9 and all your results will show the set number of decimals. So if all your results have a lot of unnecessary 0, maybe you should set the FIX mode to fewer decimal digits.

If you still have a problem with the calculation of logarithms, maybe the syntax you use is incorrect.

Try number then log
If that does not work
try log then number.

Problem with Casio FX 260 Calculator


Read the screen capture about the MODES of this calculators. DEG,RAD, and GRAD remind the user that the angle units in trigonometric function calculations and coordinate conversions are in degrees, radians or grads. They have nothing to do with the other calculations you are doing.

You can only remove DEG by changing the angle unit to RADians or GRADs. In so doing, the new unit indicator (RAD, GRAD) will be displayed instead. There is no point worrying about the angle unit indicator unless you are performing coordinate conversions or calculating trigonometric functions or the inverse trigonometric functions.

MODE 9 cancels the FIX display format: decimal are displayed with a fixed number of decimal places (set by the user). After this key sequence the decimal display format reverts to NORM(al).

PROBLEM W/ CASIO fx-260 SOLAR


Sorry, but I think you misunderstood what the manual says. See the not on the screen capture.
True the sentence is not very clear, but what it means is the following:
All modes (except COMP) will have an indicator (with the appropriate labeling) displayed. When in COMP mode the COMP indicator is not displayed.

The truth of the matter is that computation- wise you have two MODES only : the general COMPutational mode and the Standard Deviation (SD Statistics) MODE. These two are incompatible because the key layout is different.

But to compute trig functions
  1. calculator must not be in SD mode, hence it is in COMP mode
  2. An angle unit must be shown on display.
Read the screen capture about the MODES of this calculators. DEG,RAD, and GRAD remind the user that the angle units in trigonometric function calculations and coordinate conversions are in degrees, radians or grads. They have nothing to do with the other calculations you are doing.
