RADIANS

• How to use RADIANS formula?
• Examples of using RADIANS formula
• RADIANS formula not working?
• Similar formulas to RADIANS

Usage

Use the RADIANS formula with the syntax shown below, it has 1 required parameter:

=RADIANS(angle)

1. angle (required):
   The angle value in degrees that you want to convert to radians. Must be a number or a reference to a cell containing a number.

Examples

Converting degrees to radians

If you have an angle value in degrees that you need to use in a mathematical calculation that requires radians, you can use the RADIANS formula to convert it to radians.

Trigonometric calculations

Trigonometric functions such as sine, cosine, and tangent require angle values to be in radians. You can use the RADIANS formula to convert an angle value from degrees to radians before using it in a trigonometric calculation.

Common Mistakes

Missing angle argument

One of the most common mistakes is forgetting to include the angle argument in the RADIANS formula. This will result in an error or an incorrect calculation. Double check that you have included the angle argument in the correct format.

Incorrect unit of measurement

Another common mistake is using the wrong unit of measurement for the angle argument. RADIANS requires the angle to be in radians, not degrees or other units. Make sure you convert your angle to radians before using it in the formula.

Incorrect syntax

If you receive an error message, it may be due to incorrect syntax. Double check that you have entered the formula correctly, including the correct spelling and punctuation. Make sure you have included the angle argument and that it is in the correct format.

Related Formulas

The following functions are similar to RADIANS or are often used with it in a formula:

• DEGREES

  The DEGREES function converts an angle value in radians to degrees. This is useful when working with trigonometric functions that require angles in degrees. The function takes one parameter, angle, which is the angle value in radians.

• SIN

  The SIN function in Google Sheets returns the sine of a given angle in radians. Sine is a mathematical function that describes a smooth repetitive oscillation. It is commonly used in trigonometry, physics, and engineering to model phenomena such as waves, oscillations, and periodic motion.

• COS

  The COS function in Google Sheets returns the cosine of an angle provided in radians. It is commonly used in trigonometry to calculate the cosine of an angle. The function takes one parameter, the angle in radians.

• TAN

  The TAN function returns the tangent of an angle specified in radians. Tangent is the ratio of the length of the opposite side to the length of the adjacent side of a right-angled triangle. This function is commonly used in trigonometry and geometry calculations.
