    Arccovercosine

    NPM version Build Status Coverage Status dependencies

    Compute the inverse coversed cosine.

    The inverse coversed cosine is defined as

    Inverse coversed cosine.

    Installation

    npm install @stdlib/math-base-special-acovercos

    Usage

    var acovercos = require( '@stdlib/math-base-special-acovercos' );

    acovercos( x )

    Computes the inverse coversed cosine.

    var v = acovercos( 0.0 );
    // returns ~1.5708
    
    v = acovercos( -3.141592653589793/2.0 );
    // returns ~-0.6075
    
    v = acovercos( -3.141592653589793/6.0 );
    // returns ~0.4966

    If x < -2, x > 0, or x is NaN, the function returns NaN.

    var v = acovercos( 1.0 );
    // returns NaN
    
    v = acovercos( -3.14 );
    // returns NaN
    
    v = acovercos( NaN );
    // returns NaN

    Examples

    var linspace = require( '@stdlib/array-linspace' );
    var acovercos = require( '@stdlib/math-base-special-acovercos' );
    
    var x = linspace( -2.0, 0.0, 100 );
    var i;
    
    for ( i = 0; i < x.length; i++ ) {
        console.log( acovercos( x[ i ] ) );
    }
