Coversine

Compute the coversed sine.

The coversed sine is defined as

c o v e r s i n left-parenthesis theta right-parenthesis equals 1 minus sine theta

Usage

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

coversin( x )

Computes the coversed sine (in radians).

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

v = coversin( Math.PI/2.0 );
// returns 0.0

v = coversin( -Math.PI/6.0 );
// returns 1.5

Examples

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

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

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