asin
Computes the principal arcsine in radians.
Known real inputs are reduced to exact multiples of pi. Numeric inputs outside the real interval [-1,1] can produce complex principal values.
Examples
These examples use Nerdamer Notation.
Evaluate the origin.
asin(0) // → 0
Use an exact inverse-trig value.
asin(1/2) // → (1/6)*pi
