Versine

Compute the versed sine.

The versed sine is defined as

Versed sine.

Usage

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

versin( x )

Computes the versed sine of a number (in radians).

var v = versin( 0.0 );
// returns 0.0

v = versin( 3.141592653589793/2.0 );
// returns ~1.0

v = versin( -3.141592653589793/6.0 );
// returns ~0.13397

Examples

var linspace = require( '@stdlib/array/linspace' );
var TWO_PI = require( '@stdlib/constants/float64/two-pi' );
var versin = require( '@stdlib/math/base/special/versin' );

var x = linspace( 0.0, TWO_PI, 100 );
var i;

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