終於打到中文 不過係用手寫板,所以要好耐。 阿文: 我唔係住(口係)香港,所以留言個陣仲係黃昏。 希望你套莫札特漫畫早日出版,我第一個捧場!

e^log2 = 2 Suppose log2 is rational, then we can say log2=p/q where p and q are integers. Then we have e^(p/q)=2, i.e. e^p=2^q, contradicting the fact that e is transcendental. Therefore log2 is irrational.
文: I only have two idols...you and Mozart! (No order of preference) >>以你超人的想像和創意,把莫扎特傳改成連載漫畫 Looking forward to it!

路人乙 >>因為1 死左, 2 講咩都唔夠過半數支持 This is not true...if 2 proposed 98,0,1,1 he'll get 3 votes (1 from himself and 1 each from 4 and 5) because if 2 gets killed then for sure 3 will propose 100,0,0 which 4 must vote for because otherwise he's going to die. 十三點 My reasoning is similar to George's...except th...閱讀更多

張海澎 I think he needs the fact that a is a root for x^2-(nb)x+(b^2-n) => P(a,b,n) in order to conclude that P(b,nb-a,n)

SC: Nice proof! Except that in line 2 of case 2 you might want to change the =>'s to <=>'s. 張海澎: I can't think of a different proof right now, but it's something interesting to think about.
