Inverse Tangent Calculator



Formula

The formula to calculate the inverse tangent (arctangent) of a value (X) is:

\[ \text{Arctan}(X) = \tan^{-1}(X) \]

What is Inverse Tangent?

The inverse tangent function, denoted as \(\tan^{-1}(X)\), returns the angle whose tangent is X. It is used to find an angle from a given tangent value.

Example Calculation

Let's calculate the inverse tangent of a tangent value (X = 1.5):

Step 1: Calculate Arctan(1.5):

\[ \text{Arctan}(1.5) = \tan^{-1}(1.5) \approx 56.31 \text{ degrees} \]

Therefore, Arctan(1.5) ≈ 56.31 degrees.
