Covercosine
Compute the coversed cosine.
The coversed cosine is defined as
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( 3.141592653589793/2.0 );
// returns 2.0
v = covercos( -3.141592653589793/6.0 );
// returns 0.5
Examples
var linspace = require( '@stdlib/array/base/linspace' );
var TWO_PI = require( '@stdlib/constants/float64/two-pi' );
var covercos = require( '@stdlib/math/base/special/covercos' );
var x = linspace( 0.0, TWO_PI, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( covercos( x[ i ] ) );
}
