Returns the tangent of x, where x is given in radians.

Example: Tangent (double):

public static int main (string[] args) {
	// Output: ``tan (0.0) = 0.000000``
	double res = Math.tan (0.0);
	print ("tan (0.0) = %lf\n", res);

	// Output: ``tan (0.5) = 0.546302``
	res = Math.tan (0.5);
	print ("tan (0.5) = %lf\n", res);

	return 0;
}
