NAME
     __sincos — sine-cosine function

SYNOPSIS
     #include <math.h>

     void
     __sincosf(float x, float *sinp, float *cosp);

     void
     __sincos(double x, double *sinp, double *cosp);

DESCRIPTION
     The __sincos() function computes the sine and cosine of x (measured in
     radians) and stores the sine in the memory pointed to by sinp and the
     cosine in the memory pointed to by cosp.

SPECIAL VALUES
     __sincos(�0, sinp, cosp) sets *sinp to �0 and sets *cosp to +1.

     __sincos(�infinity, sinp, cosp) raises the "invalid" floating-point
     exception and sets both *sinp and *cosp to NaN.

VECTOR OPERATIONS
     If you need to apply the __sincos() function to SIMD vectors or arrays,
     using the following functions provided by the Accelerate.framework may be
     useful:

     #include <Accelerate/Accelerate.h>

     vFloat vsincosf(vFloat x, vFloat *c);
     void vvsincosf(float *s, float *c, const float *x, const int *n);
     void vvsincos(double *s, double *c, const double *x, const int *n);
