COS Formula Syntax
Example Use Case
Calculating the cosine of an angle for trigonometric modeling
Understanding the COS Formula
The COS function in Excel computes the cosine of an angle given in radians, returning a value between -1 and 1. It’s a core trigonometric function, vital for modeling waves, rotations, or geometric relationships in fields like engineering, physics, or design.
For example, inputting 1.0472 radians (60°) yields 0.5, reflecting the cosine of that angle. Use it with RADIANS to convert degrees if needed. COS is foundational for anything involving periodic or angular calculations.
Why Use COS?
COS is essential for trigonometric analysis—think pendulum motion, sound waves, or structural angles. It provides the horizontal component of an angle, making it a building block for simulations and spatial math in Excel.
Example with Sample Data
| Angle (radians) | Formula | Result |
|---|---|---|
| 1.0472 | =COS(1.0472) | 0.5 |
| 0 | =COS(0) | 1 |
| 3.1416 | =COS(3.1416) | -1 |
COS maps angles to values: 1.0472 radians (60°) gives 0.5, 0 radians gives 1. It’s a trigonometric essential.
