Cotangent
Evaluate the cotangent of a number.
Installation
npm install @stdlib/math-base-special-cot
Usage
var cot = require( '@stdlib/math-base-special-cot' );
cot( x )
Evaluates the cotangent of x
(in radians).
var v = cot( 0.0 );
// returns Infinity
v = cot( 3.141592653589793/2.0 );
// returns ~0.0
v = cot( -3.141592653589793/4.0 );
// returns ~-1.0
v = cot( 3.141592653589793/4.0 );
// returns ~1.0
v = cot( NaN );
// returns NaN
Examples
var linspace = require( '@stdlib/array-base-linspace' );
var PI = require( '@stdlib/constants-float64-pi' );
var cot = require( '@stdlib/math-base-special-cot' );
var x = linspace( -PI/2.0, PI/2.0, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( cot( x[ i ] ) );
}
