Arctan Calculator
Arctan Calculator: A Quick Guide
The Arctan Calculator is a tool designed to help users quickly compute the arctangent (inverse tangent) of a value. It is essential for solving problems in trigonometry, geometry, and engineering. This guide explains what arctan means, how the calculator works, and its practical uses.
What is Arctan?
Arctan, short for “arc tangent,” is the inverse of the tangent function. It helps find an angle when the tangent of that angle is known. For example:
- If the tangent of an angle is 1, the arctan of 1 is 45° (or \( \pi/4 \) radians).
Mathematically, the arctan function is written as:
\[ \theta = \arctan(x) \]
Where:
- \( \theta \): The angle.
- \( x \): The tangent value.
How the Arctan Calculator Works
The calculator simplifies the process of finding angles by performing the following steps:
- Input a value: Enter the tangent value you want to calculate.
- Choose the unit: Select degrees or radians for the output.
- Get the result: The calculator instantly shows the angle.
For example:
- Input: \( x = 0.5 \)
- Unit: Degrees
- Output: \[ \theta = 26.57^\circ \]
