tan, tanf - tangent function
#include <math.h> double tan(double x); float tanf(float x);
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).
The tan() function returns the tangent value.
