ATAN

The ATAN function in Google Sheets returns the inverse tangent of a value, in radians. It's an essential tool whenever you need to recover an angle from a tangent ratio in trigonometry, geometry, or physics work. Dive into our comprehensive guide to master its application.

Parameters

• value: The value for which you want to find the inverse tangent.

Step-by-Step Tutorial

1. Using ATAN with a number:

   • Example: =ATAN(0.5)
   • Result: 0.4636476090008061

2. Converting the result to degrees:

   • Example: =DEGREES(ATAN(1))
   • Result: 45

Use Cases and Scenarios

1. Geometry: Calculate the angle of a triangle when the ratio of two sides is known.
2. Motion Analysis: Determine the angle of inclination of a moving object's path.
3. Engineering: Compute slope angles in construction and design calculations.
