@stdlib/math-base-special-ahaversin v0.2.1
Archaversine
Compute the inverse half-value versed sine.
The inverse half-value versed sine is defined as
Installation
npm install @stdlib/math-base-special-ahaversin
Usage
var ahaversin = require( '@stdlib/math-base-special-ahaversin' );
ahaversin( x )
Computes the inverse half-value versed sine.
var v = ahaversin( 0.0 );
// returns 0.0
v = ahaversin( 1.0 );
// returns ~3.1416
v = ahaversin( 0.5 );
// returns ~1.5708
If x < 0
, x > 1
, or x
is NaN
, the function returns NaN
.
var v = ahaversin( 1.5 );
// returns NaN
v = ahaversin( -3.14 );
// returns NaN
v = ahaversin( NaN );
// returns NaN
Examples
var linspace = require( '@stdlib/array-base-linspace' );
var ahaversin = require( '@stdlib/math-base-special-ahaversin' );
var x = linspace( 0.0, 1.0, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( ahaversin( x[ i ] ) );
}
