Covercosine

Compute the coversed cosine.

The coversed cosine is defined as

c o v e r c o s left-parenthesis theta right-parenthesis equals 1 plus sine theta

Usage

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

covercos( x )

Computes the coversed cosine (in radians).

var v = covercos( 0.0 );
// returns 1.0

v = covercos( Math.PI/2.0 );
// returns 2.0

v = covercos( -Math.PI/6.0 );
// returns 0.5

Examples

var linspace = require( '@stdlib/math/utils/linspace' );
var covercos = require( '@stdlib/math/base/special/covercos' );

var x = linspace( 0.0, 2.0*Math.PI, 100 );
var i;

for ( i = 0; i < x.length; i++ ) {
    console.log( covercos( x[ i ] ) );
}
