35.Sh NAME
36.Nm sin ,
37.Nm sinf
38.Nd sine functions
39.Sh LIBRARY
40.Lb libm
41.Sh SYNOPSIS
42.In math.h
43.Ft double
44.Fn sin "double x"
45.Ft float
46.Fn sinf "float x"
47.Sh DESCRIPTION
48The
49.Fn sin
50and the
51.Fn sinf
52functions compute the sine of
53.Fa x
54(measured in radians).
55A large magnitude argument may yield a result with little
56or no significance.
57.Sh RETURN VALUES
58The
59.Fn sin
60and the
61.Fn sinf
62functions return the sine value.
