Let \(x\) be an angle such that \(P\) is the terminal point of \(x\):

Some of the points \(Q, R, S, T\) can be the terminal points of \(\frac{x}{2}\). What are these points? 

And there is also a second part of this question, if someone can solve this too it would be very helpful (although I am very close to finishing).

Assume that \(\cos(\theta/2) < 0\). Then if \(\[\text{Terminal point of } \frac{\theta}{2} = (a_1, a_2),\]\), what is \(a_1\) and \(a_2\)?
