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

SYNOPSIS
       #define _GNU_SOURCE
       #include <&lt;math.h>&gt;

       void sincos(double x, double *sin, double *cos);
       void sincosf(float x, float *sin, float *cos);
       void sincosl(long double x, long double *sin, long double *cos);

       Link with -lm.

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.
