Math 415

Example

The following example displays the arc sine for several values.

trace(Math.asin(-1)); // output: -1.5707963267949

trace(Math.asin(0)); // output: 0

trace(Math.asin(1)); // output: 1.5707963267949

atan (Math.atan method)

public static atan(tangent:Number) : Number

Computes and returns the value, in radians, of the angle whose tangent is specified in the

parameter

tangent. The return value is between negative pi divided by 2 and positive pi

divided by 2.

Availability: ActionScript 1.0; Flash Lite 2.0 - In Flash Player 4, the methods and properties

of the Math class are emulated using approximations and might not be as accurate as the non-

emulated math functions that Flash Player 5 supports.

Parameters

tangent:Number - A number that represents the tangent of an angle.

Returns

Number - A number between negative pi divided by 2 and positive pi divided by 2.

Example

The following example displays the angle value for several tangents.

trace(Math.atan(-1)); // output: -0.785398163397448

trace(Math.atan(0)); // output: 0

trace(Math.atan(1)); // output: 0.785398163397448
