Re: [分析] 初微(6)
※ 引述《PttFund (批踢踢基金)》之銘言：
: If
: c_0 + c_1/2 + ... + c_n/(n+1) = 0,
: where c_i is real. Prove that
: c_0 + ... + c_n x^n = 0
: has at least one root between 0 and 1.
n (c_i)x^i+1
By assumption => x=0 and x=1 are roots of Σ -----------
i=0 i + 1
Roll's Thm. => there is x_0 between 0 and 1 s.t.
n
Σ (c_i)(x_0)^i = 0
i=0

總是去意識著別人的評價，這樣的生活方式、生活態度不是我所要的。
我想要過的是---自己所能接受、自己可以認同的生活方式..
