NAME
tan - 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 radians). 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.
