System.Math.Asin Method

Returns the angle whose sine is the specified double. [Edit]

public static double Asin (double d)

Parameters

d
A double representing a sine, where -1 <= d <= 1. [Edit]

Returns

A double containing the value of an angle, theta, measured in radians, for which d is the sine, such that -pi/2 <= theta <= pi/2. If d < -1, d > 1, or d = double.NaN, returns double.NaN . [Edit]

Remarks

Note:

A positive return value represents a counterclockwise angle from the positive x-axis; a negative return value represents a clockwise angle.

Multiply the return value by 180/pi to convert from radians to degrees.
