1 radian = 57° (Approx) The value of sinθ and tanθ 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°. 1° < 57°, so sin 1° < sin 57° or sin 1° < sin 1° Hence, 1 is incorrect. 1° < 57°, so cos 1° > cos 57° or cos 1° > cos 1° Hence, 2 is incorrect. 1° < 57°, so tan 1° < tan 57° or tan 1° < tan 1° Hence, 3 is incorrect.
