We know that [tex] S_x = \frac{\hbar}{2} \left( |+ \rangle \langle - | + | - \rangle \langle+| \right)[/tex](adsbygoogle = window.adsbygoogle || []).push({});

But what is [tex]|S_x ; + \rangle[/tex]?

I think my text says [tex]|S_x ; + \rangle = \frac{1}{\sqrt{2}} \left( |+ \rangle + | - \rangle \right)[/tex] but i dont know how they got this.

I feel like this is a trivial question but I'm not sure how one finds [tex]|S_x ; + \rangle[/tex]
