cotd

Compute the cotangent of an angle measured in degrees.

Usage

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

cotd( x )

Evaluates the cotangent of x (in degrees).

var v = cotd( 0.0 );
// returns Infinity

v = cotd( 60.0 );
// returns ~0.58

v = cotd( 90.0 );
// returns 0.0

v = cotd( NaN );
// returns NaN

Examples

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

var x = linspace( -180, 180, 100 );

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