#include <math.h>
void
  
  sincos(double
    x, double *s,
    double *c);
void
  
  sincosf(float
    x, float *s,
    float *c);
void
  
  sincosl(long
    double x, long double
    *s, long double
    *c);
sincos(), sincosf(), and
  sincosl() functions compute the sine and cosine of
  x. Using these functions allows argument reduction to
  occur only once instead of twice with individual invocations of
  sin() and cos(). Like
  sin() and cos(), a large
  magnitude argument may yield a result with little or no significance.
sincos(),
  sincosf(), and sincosl(), the
  memory pointed to by *s and *c are
  assigned the values of sine and cosine, respectively.
