DuckDB npm Account Compromised in Continuing Supply Chain Attack
Ongoing npm supply chain attack spreads to DuckDB: multiple packages compromised with the same wallet-drainer malware.
@stdlib/math-base-special-tan
Advanced tools
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
Evaluate the tangent of a number.
The tangent is defined as
npm install @stdlib/math-base-special-tan
var tan = require( '@stdlib/math-base-special-tan' );
Evaluates the tangent of a number
(in radians).
var v = tan( 0.0 );
// returns ~0.0
v = tan( -3.141592653589793/4.0 );
// returns ~-1.0
v = tan( 3.141592653589793/4.0 );
// returns ~1.0
v = tan( NaN );
// returns NaN
var linspace = require( '@stdlib/array-base-linspace' );
var PI = require( '@stdlib/constants-float64-pi' );
var tan = require( '@stdlib/math-base-special-tan' );
var x = linspace( -PI/2.0, PI/2.0, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( tan( x[ i ] ) );
}
#include "stdlib/math/base/special/tan.h"
Evaluates the tangent of a number
(in radians).
double y = stdlib_base_tan( -3.141592653589793 / 4.0 );
// returns ~-1.0
The function accepts the following arguments:
[in] double
input value.double stdlib_base_tan( const double x );
#include "stdlib/math/base/special/tan.h"
#include <stdio.h>
int main( void ) {
const double x[] = { 0.0, 0.523, 0.785, 1.047, 3.14 };
double y;
int i;
for ( i = 0; i < 5; i++ ) {
y = stdlib_base_tan( x[ i ] );
printf( "tan(%lf) = %lf\n", x[ i ], y );
}
}
@stdlib/math-base/special/cos
: compute the cosine of a number.@stdlib/math-base/special/sin
: compute the sine of a number.This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
