UPSC 2016 CDS II Math Paper

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.
