Cos / Computation Layer

Calculate the cosine of angle values (in radians) in a column. Similar to pandas cos(), numpy.cos(), or R's cos() function.

Mathematical form: $y_{i} = cos (x_{i})$ where:

Input domain: all real numbers (in radians)
Output range: $y_{i} \in [- 1, 1]$
Period: $2 π$ radians
Key points: $cos (0) = 1$ , $cos (π) = - 1$

Common applications:

Wave analysis
Signal processing
Directional computations
Periodic phenomena modeling
Phase calculations
Circular motion

Note: Input angles must be in radians. For degrees, convert using degrees × (π/180).

column

The numeric column containing angles in radians. Examples:

0 → 1.0 (horizontal)
π/2 (1.5708...) → 0.0 (vertical)
π (3.1416...) → -1.0 (opposite)
π/3 (1.0472...) → 0.5 (60 degrees)

Common to first normalize angles to [0, 2π] range

Name for the new column. If not provided, the system generates a unique name. If AsColumn matches an existing column, the existing column is replaced. The name should follow valid column naming conventions.
