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 correct calculator mode?
In most cases, the standard mode for a scientific calculator is degree mode, but if you frequently change between different forms of angle measurement, then you need to learn how to switch modes.
What is the default mode for calculator?
By default, Calculator runs in standard mode, which resembles a four-function calculator.
Should I use RAD or DEG?
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.
Why does my calculator say DEG?
It signifies “Radian”, a unit of measuring angles. Another one is “Degree” (if you tap “RAD” it will change to “DEG”). So the text on the top left signifies what mode the calculator is in, radian or degree.
Should my calculator be in degrees or radians for Sohcahtoa?
Example 5: Evaluate the trigonometric function using a calculator. Because these angles are in radian measure, our calculator should be converted in RADIAN MODE.
How do I know if I have SOH CAH TOA?
SOHCAHTOA is a mnemonic device helpful for remembering what ratio goes with which function.
- SOH = Sine is Opposite over Hypotenuse.
- CAH = Cosine is Adjacent over Hypotenuse.
- TOA = Tangent is Opposite over Adjacent.
How do I get my Casio calculator off FX?
How to reset Casio fx-991ES or fx-82ES?
- Turn the calculator on with the ON button. There is no hardware reset button on the back.
- SHIFT 9 to enter Reset.
- 3 to select the Reset All option.
- = to confirm the reset.
- AC to return to normal calculation, or SHIFT AC to turn the calculator off.
What is E in calculator?
On a calculator display, E (or e) stands for exponent of 10, and it’s always followed by another number, which is the value of the exponent. For example, a calculator would show the number 25 trillion as either 2.5E13 or 2.5e13. In other words, E (or e) is a short form for scientific notation.
What does G mean on calculator?
2 Answers. 2. 1. Gradian is a unit of measurement of angles. 100 grad=90o=π2 radians.
What does Sohcahtoa mean?
“SOHCAHTOA” is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent, (1) (2)
Is Sohcahtoa a trigonometry?
Sohcahtoa: SOHCAHTOA is a mnemonic device that is used in mathematics to remember the definitions of the three most common trigonometric functions.Sine, cosine, and tangent are the three main functions in trigonometry. They’re all based on ratios obtained from a right triangle.
Does Sohcahtoa work on non right triangles?
For right-angled triangles, we have Pythagoras’ Theorem and SOHCAHTOA. However, these methods do not work for non-right angled triangles. For non-right angled triangles, we have the cosine rule, the sine rule and a new expression for finding area.
