Arctan or ATAN function is one of many mathematical functions commonly used in Excel. To understand this function better, let's follow the article below by TechTipsSoftware.com.

1. Purpose of the Function

The ATAN function is one of the trigonometric functions computed using Excel spreadsheets. It returns the arctangent, or the inverse tangent of a number. The returned angle is measured in radians and ranges from -π/2 to π/2.

2. Usage of the Function

Formula:

ATAN(number to be calculated)

Where: The number to be calculated is the tangent of the angle you want to calculate.

3. Examples of the Function

The ATAN function helps you calculate the radian angle of a tangent. By using the formula =ATAN(number to calculate), you can find the angle in radians.

To convert the angle from radians to degrees, you can use the DEGREES function with the formula =DEGREES(radian angle to convert to degrees) to calculate the angle in degree units.

So, you've successfully utilized the ATAN function in Excel to calculate the Arctan for a number.

Thank you for following our article on the Arctan function in Excel and how to use Arctan by TechTipsSoftware.com. We hope you can proficiently apply the Arctan function in practical applications.

Frequently Asked Questions

What is the purpose of the ATAN function in Excel and how is it used?

The ATAN function in Excel serves to calculate the arctangent, or inverse tangent, of a number. It returns the angle in radians, which ranges from -π/2 to π/2. The formula used is =ATAN(number), where 'number' is the tangent of the angle you wish to compute.

How can I convert radians to degrees after using the ATAN function in Excel?

To convert the angle obtained from the ATAN function from radians to degrees, you can utilize the DEGREES function. The formula would be =DEGREES(radian angle), allowing you to express the angle in degree units after calculating it in radians.

What is the expected output of the ATAN function when given a specific number?

When the ATAN function is applied to a specific number, it returns the angle in radians whose tangent is the provided number. This enables users to determine the angle corresponding to a given tangent value, facilitating various trigonometric calculations in Excel.
