.NET Framework 4.6 and 4.5
Returns the angle whose sine is the specified number.
(in mscorlib.dll) System.Runtime.Extensions
static member Asin :
d:float -> float
- Type: System.Double
A number representing a sine, where d must be greater than or equal to -1, but less than or equal to 1.
Type: System.DoubleAn angle, θ, measured in radians, such that -π/2 ≤ θ ≤ π/2
NaN if d < -1 or d > 1 or d equals NaN.
A positive return value represents a counterclockwise angle from the x-axis; a negative return value represents a clockwise angle.
Multiply the return value by 180/Math.PI to convert from radians to degrees.
The following example uses Asin to assist in the computation of the inner angles of a given trapezoid.
