+.Nd bessel functions of first and second kind
+.Sh SYNOPSIS
+.Fd #include <math.h>
+.Ft double
+.Fn j0 "double x"
+.Ft double
+.Fn j1 "double x"
+.Ft double
+.Fn jn "int n" "double x"

+.Fn yn "int n" "double x"
+.Sh DESCRIPTION
+The functions
+.Fn j0
+and
+.Fn j1
+compute the
+.Em Bessel function of the first kind of the order
+0 and the
+.Em order
+1, respectively,
+for the
+real value
+.Fa x ;
+the function
+.Fn jn
+computes the
+.Em Bessel function of the first kind of the integer order
+.Fa n
+for the real value
+.Fa x .
+.Pp
+The functions
+.Fn y0
+and
+.Fn y1
+compute the linearly independent
+.Em Bessel function of the second kind of the order
+0 and the
+.Em order
+1, respectively,
+for the positive
+.Em integer
+value
+.Fa x
+(expressed as a double);
+the function
+.Fn yn
+computes the
+.Em Bessel function of the second kind for the integer order
+.Fa n
+for the positive 
+.Em integer
+value
+.Fa x
+(expressed as a double).
+.Sh RETURN VALUES
+If these functions are successful,
+the computed value is returned. On the
+.Tn VAX
+and
+.Tn Tahoe
+architectures,
+a negative
+.Fa x
+value
+results in an error; the global
+variable
+.Va errno
+is set to
+.Er EDOM
+and a reserve operand fault is generated.
+.Sh SEE ALSO

+.Xr infnan 3
+.Sh HISTORY
+A set of these functions
+function appeared in
+.At v7 .
