Export assignment sincos

• sincos(out: Collection, x: number): Collection
• sincos(x: number): Collection

• Simultaneously computes the sine and cosine of a number.

  Parameters

  • out: Collection

    destination array

  • x: number

    input value (in radians)

  Returns Collection

  sine and cosine

  Example

  var Float64Array = require( `@stdlib/array/float64` );
  
  var out = new Float64Array( 2 );
  
  var v = sincos( out, 0.0 );
  // return <Float64Array>[ ~0.0, ~1.0 ]
  
  var bool = ( v === out );
  // returns true

• Simultaneously computes the sine and cosine of a number.

  Parameters

  • x: number

    input value (in radians)

  Returns Collection

  sine and cosine

  Example

  var v = sincos( 0.0 );
  // returns [ ~0.0, ~1.0 ]

  Example

  var v = sincos( 3.141592653589793/2.0 );
  // returns [ ~1.0, ~0.0 ]

  Example

  var v = sincos( -3.141592653589793/6.0 );
  // returns [ ~-0.5, ~0.866 ]

  Example

  var v = sincos( NaN );
  // returns [ NaN, NaN ]
