ATAN Formula Syntax
Example Use Case
Finding the angle (in radians) from a tangent value for trigonometric analysis
Understanding the ATAN Formula
The ATAN function in Excel calculates the arctangent (inverse tangent) of a number, returning an angle in radians between -π/2 and π/2. It’s perfect for finding angles from tangent ratios, a frequent task in trigonometry for navigation, engineering, or graphing slopes.
Unlike ACOS or ASIN, ATAN accepts any real number, reflecting tangent’s unbounded nature. Use it with DEGREES for degree outputs. It reverses TAN, making it essential for angle-solving in practical scenarios.
Why Use ATAN?
ATAN is key for angle calculations from slopes or ratios. It’s used in robotics, surveying, or any field needing precise angular data from tangents. Its broad input range ensures flexibility across applications.
Example with Sample Data
| Tangent | Formula | Result (radians) |
|---|---|---|
| 1 | =ATAN(1) | 0.7854 |
| 0 | =ATAN(0) | 0 |
| -1 | =ATAN(-1) | -0.7854 |
ATAN turns tangents into angles: 1 gives ~0.7854 radians (45°), mirroring positives and negatives. It’s a reliable angle finder.
