## What is Inverse Tan Calculator?

An inverse tangent calculator, also known as an arctan calculator, is a tool used to calculate the arctangent of a given value. The arctangent function is the inverse of the tangent function and is used to determine the angle of a right triangle when given the lengths of its sides. An arctan calculator can be useful in a variety of fields, including engineering, physics, and math.

**Formula**

The formula for calculating the arctangent of a value is:

Arctan(x) = C

Where x is the value and C is the angle in radians or degrees.

**Example**

Suppose you want to find the arctangent of 0.5. Using the formula, the result would be:

Arctan(0.5) = 0.464 radians (rounded to 3 decimal places)

**How to Calculate**

To use an inverse tangent calculator, input the value you want to find the arctangent of and select whether the result should be in radians or degrees. Once you click the “Calculate” button, the calculator will use the arctangent formula to compute the result.

**FAQs**

**What is the arctangent function?**

The arctangent function, also known as the inverse tangent function, is the inverse of the tangent function. It is used to determine the angle of a right triangle when given the lengths of its sides.

**How is the arctangent different from the tangent function?**

The tangent function is used to find the ratio of the opposite side to the adjacent side of a right triangle. The arctangent function, on the other hand, is used to find the angle when given the ratio of the opposite side to the adjacent side.
