TAN(3)                     BSD Programmer's Manual                      TAN(3)

NAME

     tan, tanf - tangent function

LIBRARY

     libm

SYNOPSIS

     #include <math.h>

     double
     tan(double x);

     float
     tanf(float x);

DESCRIPTION

     The tan() and tanf() functions compute the tangent of x (measured in ra-
     dians). A large magnitude argument may yield a result with little or no
     significance. For a discussion of error due to roundoff, see math(3).

RETURN VALUES

     The tan() function returns the tangent value.

SEE ALSO

     acos(3), asin(3), atan(3), atan2(3), cos(3), cosh(3), math(3), sin(3),
     sinh(3), tanh(3)

STANDARDS

     The tan() function conforms to ANSI X3.159-1989 ("ANSI C89").
