ArcSin / Computation Layer

Calculate the inverse sine (arcsin) of values in a column. Similar to pandas arcsin(), numpy.arcsin(), or R's asin() function. Returns angles in radians.

Mathematical form: $$y_i=\arcsin (x_i)={\sin }^{-1}(x_i)$$ where:

• Input domain: $x_i\in [-1,1]$
• Output range: $y_i\in [-\frac{\pi }{2},\frac{\pi }{2}]$

Common applications:

• Angle recovery from projections
• Elevation angle calculations
• Orbital mechanics
• Optics and wave analysis
• Mechanical motion analysis
• Quality control (process deviation)

Note: Returns null for inputs outside [-1, 1] and preserves existing nulls. Results are in radians.
