#include <iostream>
#include <cmath>

using namespace std;

int main()
{
	cout << "tanh(1) = " << tanh(1) << endl;
	cout << "tanh(-1) = " << tanh(-1) << endl;
	cout << "tanh(0.0) = " << tanh(0.0) << endl;
	cout << "tanh(-0.0) = " << tanh(-0.0) << endl;
	cout << "tanh(log(2.0)) = " << tanh(log(2.0)) << endl;

	return 0;
}

/*
run:

tanh(1) = 0.761594
tanh(-1) = -0.761594
tanh(0.0) = 0
tanh(-0.0) = -0
tanh(log(2.0)) = 0.6
