Question

Find which of the following given numbers is greater
$\sin 2or\cos 3$?

Answer 1

For that we have to careful about that the angle is in radian so first we have convert it into in degree so for that we just have to multiply the radian angle with $57$ which is standard method then we have a rough idea

so, $\cos {(171}^0)$ and $\sin {(114}^0)$ these things we actually have so just simple looking that we say $\sin 2$ is greater because it is positive and $\cos 3$ is negative.
