@stdlib/math-base-special-secd v0.1.0

secd

Compute the secant of an angle measured in degrees.

Installation

npm install @stdlib/math-base-special-secd

Usage

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

secd( x )

Computes the secant of x (in degrees).

var v = secd( 30 );
// returns ~1.15

v = secd( 45 );
// returns ~1.41

v = secd( 60 );
// returns ~2.0

v = secd( 90 );
// returns 16331239353195370

v = secd( 0 );
// returns 1.0

v = secd( NaN );
// returns NaN

Examples

var linspace = require( '@stdlib/array-base-linspace' );
var secd = require( '@stdlib/math-base-special-secd' );

var x = linspace( 1.1, 5.1, 100 );

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