## How do I get the D off my Casio calculator?

Casio models: Press [SHIFT][MODE][6:Fix]. You are then prompted to enter a number between 0 and 9. The number you enter fixes the number of decimal digits your results will have.

## How do I get rid of GT on my calculator?

To clear the grand total memory, press the GT key while displaying the grand total. The basic use of the Mark-Up (MU) key is identical to using the % key to add a desired margin percentage to the input number.

## Where is the mode button on a Casio calculator?

Locate the number beside “Deg” or “Degrees” and press it to change the mode of your calculator. On some calculator models, including the Casio FX-4800P, the FX-5500LA, V.P.A.M. models and others, you might need to press the “Mode” button twice or more until you get to the angle mode-selection screen.

## What mode should my calculator be in?

Almost all calculators come with both DEG & RAD mode. You should use the mode which matches with the given data in the question. For example: if we need to find cos(v) and v=60°, then use degree mode because given angle is in degree. If the given angle is in radians then use RAD mode.

## What is the normal calculator mode?

Normal 1 (Norm 1) mode uses scientific notation for any number less than 0.01 but greater than −0.01, and otherwise displays answers to however decimal places they have, subject to the maximum that will fit on the display. This mode is entered using (SETUP) (Norm) .

## Should my calculator be in radians or degrees for physics?

You should use radians when you are looking at objects moving in circular paths or parts of circular path. In particular, rotational motion equations are almost always expressed using radians. The initial parameters of a problem might be in degrees, but you should convert these angles to radians before using them.

## Should my calculator be in radians or degrees for chemistry?

​No it doesn’t matter. All of your calculations can be done in degree mode. Some trigonometry calculations have to be done in radian mode.

## Should my calculator be in degrees or radians for calculus?

Calculus is always done in radian measure. Degree (a right angle is 90 degrees) and gradian measure (a right angle is 100 grads) have their uses. Outside of the calculus they may be easier to use than radians. … This keeps all the important numbers like the sine and cosine of the central angle, on the same scale.
