J0(3M)                  COMMAND REFERENCE                  J0(3M)



NAME
     j0, j1, jn, y0, y1, yn - bessel functions

SYNOPSIS
     #include <math.h>

     double j0 (x)
     double x;

     double j1 (x)
     double x;

     double jn (n, x)
     double x;

     double y0 (x)
     double x;

     double y1 (x)
     double x;

     double yn (n, x)
     double x;

DESCRIPTION
     These functions calculate Bessel functions of the first and
     second kinds for real arguments and integer orders.

FILES
     /usr/lib/libm.a          Mathematical library functions.

DIAGNOSTICS
     Negative arguments cause y0, y1, and yn to return a huge
     negative value and set errno to EDOM.

     intro(2), perror(3f).
