The formula to calculate the inverse tangent (arctangent) of a value (X) is:
\[ \text{Arctan}(X) = \tan^{-1}(X) \]
Where:
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.
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.
