答案里面说P70对三个situations来说都是相同的。 想问这里是为什么?
是算出来的还是有一个这么的definition
The curve ,tp70 for t E [0,2] is a line for DM and a convex curve lying below the line for CF (since they intersect
at t = 0 and t = 2) 这里的话 也是要做图还是说这是一个已经证明了的现象 考试的时候记住就好?, so CF < DM, For !LT, we find that d70 = 6,615,155-6,396,609 = 218,546 while d71 =6,396,609-6,164,663 = 231,946, so dx is increasing (whereas it is level for DM), so PllT > pM 这里完全不明白。
谢谢大家
