一道简单的数学题
看到@矢作萌夏 在主区发的贴子，我很感兴趣，于是随手再原创了一道题。很简单，路过的葱油不妨试试。
现在时间不早了，我先去睡觉，明天看到有人做出来了，我就点评一下。
已知1<a1<a2<a3，求证：
（a1-1）a3/(a1+a2)-a1^2/(a2+a3)+1/2>0

Maybe the artist is just good at drawing. But I doubt about quite a few statements there.
Maybe she just likes to think about it. But from Disney film, oh well........
It would not be as odd to me if not two characters from Disney film. Frankly, not unlike myself before, when I used to be more sexually charged (before the adverse effects)
