I have stuck on this problem for long time(adsbygoogle = window.adsbygoogle || []).push({});

[tex] sin^2 \alpha = \frac{\alpha}{2} [/tex]

I never meet this kind of problem before, and I have no idea about this. Could someone tell me how to solve this kind of problem?

Thanks in advance.

(Ans: [tex] \alpha = 1.39 rad [/tex])
