## Should I set my calculator to degrees or radians?

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.

You should use degrees when you are measuring angles using a protractor, or describing a physical picture..

## What mode should my calculator be in for sin and cos?

For graphing calculators, press “Mode.” If you are using degrees (generally, if you are in geometry), the calculator should be set to degrees or “deg.” If you are using radians (precalculus or trigonometry), it should be set to radians or “rad.” Press the “Cos” button, generally found in the middle of the calculator.

## What is the degree symbol on a calculator?

Within ANGLE, you will find: the degree symbol (°), the minute symbol ( ′), the radian symbol ( r ), and the symbol to change to Degrees-Minutes-Seconds (►DMS). Above the ^ key you will find the π symbol. In MATH, you will find the symbol to change to a decimal form (►Dec).

## How do I fix my scientific calculator to normal?

Explanation:TI models: Press [SCI/ENG]. The display shows FLO SCI ENG. Use the left arrow key to select FLO. … Casio models: Press [SHIFT][MODE][6:Fix]. You are then prompted to enter a number between 0 and 9. … Sharp models: Press [SET UP] [1:FSE] [0:FIX]. This sets the calculator to use a fixed number of decimal places.

## How do you use sin cos and tan on a calculator?

Find the sine, cosine, or tangent of an angle. Simply enter the value of the angle in degrees and push the “sin,” “cos,” or “tan” button. Convert the sine of an angle into the measure of the angle. Input the value of the sine, then hit the button that says “arcsin,” or “sin-1.”

## How do you solve Sin Cos Tan on a calculator?

Press and check that your calculator is set to Degree mode. To convert a trigonometric ratio back to an angle measure, use the inverse function found above the same key as the function. Press , select the inverse function, either [SIN 1], [COS 1], or [TAN 1], and enter the ratio. Then, close the parentheses and press .

## How do you convert degrees to minutes and seconds on a calculator?

Follow these steps to convert decimal degrees to DMS :For the degrees use the whole number part of the decimal.For the minutes multiply the remaining decimal by 60. Use the whole number part of the answer as minutes.For the seconds multiply the new remaining decimal by 60.

## 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.

## Why do we convert degrees to radians?

Degree (a right angle is 90 degrees) and gradian measure (a right angle is 100 grads) have their uses. … The length of the arc subtended by the central angle becomes the radian measure of the angle. This keeps all the important numbers like the sine and cosine of the central angle, on the same scale.

## Why my Casio calculator is not working?

Check the battery is put in correctly and not with reversed polarity. Check the battery is new and in date. Clean the contacts of the battery holder.

## What is the difference between degrees and radians?

Radian by definition is the angle subtended by an arc whose length is equal to radius of the circle. This unit has a physical relevance. Whereas degree has no such direct physical relevance, the complete angle of circle is divided into 360 degrees. Nothing more.

## How do you add minutes and seconds on a calculator?

For example, add the times 1:30:45 and 2:45:20 together.Add hours, minutes, and seconds separately: hours = 1 + 2 = 3 hours. … Seconds are greater than 60, so add 1 minute and subtract 60 seconds: minutes = 75 + 1 = 76 minutes. … Minutes are greater than 60, so add 1 hour and subtract 60 minutes: hours = 3 + 1 = 4 hours.
