PROBLEM W/ CASIO fx-260 SOLAR

HELP!
I cannot get out of the DEG or RAD or GRA modes. I am trying to get back to COMP mode which should be indicated by an absence of display in the mode indicator. MODE 9 does nothing

    I have the same problem. The can only get deg, rad, and gra. I cannot get norm, sci, fix, or comp. How can this problem be solved?

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.

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).

How do I clear "DEG" from display?


You can switch between Rads/Deg/Grads. Deg is the one you want to use. So, to answer your question, the "DEG" is suppose to be there so that you know what mode you are using. If you don't have the manual, here it is:

When you are in "comp"


The "Deg" indicates degrees are the unit used for trigonometric calculations. You can use [MODE] [5] to switch to radians or [MODE] [6] for grade. [MODE] [4] switches back to degrees. This is independent of "Comp" mode.

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.
