1 radian = 57° (Approx.) Remember: The value of sinθ increases as the value of θ increases from 0° to 90° and the value of cosθ decreases as the value of θ increases from 0° to 90°. Now, 1° < 57°,so sin 1° < sin 57° or sin 1° < sin 1 Hence, statement 1 is incorrect. Again 1° < 57°,so cos 1° < cos 57° or cos 1° < cos 1 Hence, statement 2 is incorrect.
