# Arctan Calculator

The Arctan Calculator is designed to determine the angle whose tangent is a given number. This function, commonly known as the inverse tangent, is crucial for solving problems where the angle needs to be determined based on the tangent ratio. This could be in fields ranging from astronomy to computer graphics, where angle calculations are essential.

### Formula of Arctan Calculator

The calculation of arctangent, or inverse tangent, depends on whether the result is needed in radians or degrees:

• Value: The tangent of the angle.

For Degrees

• Arctan (Degrees) = arctan(Value) × (180 / π)
• Value: The tangent of the angle.
• π (Pi): A mathematical constant approximately equal to 3.14159.

These formulas provide a straightforward method for users to convert a known tangent value into an angle, either in radians, the standard unit of angular measure used in mathematics, or degrees, commonly used in many practical applications.

#### General Terms and Conversion Table

To aid in understanding, here’s a table of terms commonly associated with the Arctan Calculator and trigonometric calculations:

### Example of Arctan Calculator

For practical illustration, consider calculating the angle for a tangent value of 1:

• Arctan (Degrees) = arctan(1) × (180 / π) = 45 degrees
