coth
Compute the hyperbolic cotangent of a number.
Installation
npm install @stdlib/math-base-special-coth
Usage
var coth = require( '@stdlib/math-base-special-coth' );
coth( x )
Computes the hyperbolic cotangent of x
.
var v = coth( 0.0 );
// returns Infinity
v = coth( 2.0 );
// returns ~1.0373
v = coth( -2.0 );
// returns ~-1.0373
v = coth( NaN );
// returns NaN
Examples
var linspace = require( '@stdlib/array-base-linspace' );
var coth = require( '@stdlib/math-base-special-coth' );
var x = linspace( -10.0, 10.0, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( coth( x[ i ] ) );
}
C APIs
Usage
#include "stdlib/math/base/special/coth.h"
stdlib_base_coth( x )
Computes the hyperbolic cotangent of double-precision floating-point number x
.
double out = stdlib_base_coth( 2.0 );
// returns ~1.0373
out = stdlib_base_coth( -2.0 );
// returns ~-1.0373
The function accepts the following arguments:
- x:
[in] double
input value.
double stdlib_base_coth( const double x );
Examples
#include "stdlib/math/base/special/coth.h"
#include <stdio.h>
int main( void ) {
const double x[] = { -4.0, -3.11, -2.22, -1.33, -0.44, 0.44, 1.33, 2.22, 3.11, 4.0 };
double v;
int i;
for ( i = 0; i < 10; i++ ) {
v = stdlib_base_coth( x[ i ] );
printf( "coth(%lf) = %lf\n", x[ i ], v );
}
}
