NAME
       sincos, sincosf, sincosl - calculate sin and cos simultaneously

SYNOPSIS
       #include <math.h>

       double sincos(double x, double *sin, double *cos);

       float sincosf(float x, float *sin, float *cos);

       long double
       sincosl(long double x, long double *sin, long double *cos);

DESCRIPTION
       Several	applications  need sine and cosine of the same angle x.	 This
       function computes both at the same time, and stores  the	 results  via
       the given pointers.

CONFORMING TO
       This function is a GNU extension.
