41.Nd tangent functions
42.Sh SYNOPSIS
43.Fd #include <math.h>
44.Ft double
45.Fn tan "double x"
46.Ft float
47.Fn tanf "float x"
48.Sh DESCRIPTION
49The
50.Fn tan
51and the
52.Fn tanf
53functions compute the tangent of
54.Fa x
55(measured in radians).
56A large magnitude argument may yield a result
57with little or no significance.
58For a discussion of error due to roundoff, see
59.Xr math 3 .
60.Sh RETURN VALUES
61The
62.Fn tan
63function returns the tangent value.
64.Sh SEE ALSO
65.Xr acos 3 ,
66.Xr asin 3 ,
67.Xr atan 3 ,
