1. ## Math problem 2

This is another part of my book that is hard:

Decide the angle x between pi/2 and pi so that sin x= sin pi/14

Later the book say that the answer is in this form:

x= a pi/b where a/b is a simplified fraction.

I hope everyone understand! Please, don't just say the answer to me i want to understand how I do it

I think you can directly compare the sin values so x=pi/14, then a/b=1/14

The angle $\pi/14$ is not between $\pi/2$ and $\pi$, as the problem requires.
